Variables

The fundamental behavior of qmake is influenced by variable declarations that define the build process of each project. Some of these declare resources, such as headers and source files, that are common to each platform. Others are used to customize the behavior of compilers and linkers on specific platforms.

Platform-specific variables follow the naming pattern of the variables which they extend or modify, but include the name of the relevant platform in their name. For example, a makespec may use QMAKE_LIBS to specify a list of libraries that each project needs to link against, and QMAKE_LIBS_X11 would be used to extend this list.

ANDROID_ABIS

Specifies a list of Android target ABIs. Valid values are: armeabi-v7a, arm64-v8a, x86, x86_64.

You can provide the ABIs as a qmake argument:

 qmake ANDROID_ABIS="armeabi-v7a arm64-v8a"

ANDROID_API_VERSION

Specifies the Android API level number. For more information, see Android Build Numbers.

ANDROID_APPLICATION_ARGUMENTS

Specifies extra command-line arguments to the Android app using the AndroidManifest.xml with the tag "android.app.arguments". This takes a string of arguments:

 ANDROID_APPLICATION_ARGUMENTS = "arg1 arg2 arg3"

ANDROID_BUNDLED_JAR_DEPENDENCIES

This is useful when writing a Qt module. It specifies a list of pre-bundled dependencies used by the module in a .jar format, for example:

 ANDROID_BUNDLED_JAR_DEPENDENCIES += jar/Qt6Android.jar

ANDROID_DEPLOYMENT_DEPENDENCIES

By default, androiddeployqt will detect the dependencies of your application. However, since run-time usage of plugins cannot be detected, there could be false positives, as your application might depend on any plugin that is a potential dependency. If you want to minimize the size of your APK, it's possible to override the automatic detection using the this variable. This should contain a list of all Qt files which need to be included, with paths relative to the Qt install root.

ANDROID_DEPLOYMENT_SETTINGS_FILE

Specifies the path to the android-deployment-settings.json file needed by androiddeployqt and androidtestrunner. This overrides the path to the settings file generated by qmake, thus you have to make sure to provide a valid settings file.

ANDROID_EXTRA_LIBS

A list of external libraries that will be copied into your application's libs folder and loaded on start-up. This can be used, for instance, to enable OpenSSL in your application. For more information, see Adding OpenSSL Support for Android.

To include external libraries for multiple ABIs, where each ABIs has its own directory, use the following:

 for (abi, ANDROID_ABIS): ANDROID_EXTRA_LIBS += $$PWD/$${abi}/library_name.so

Otherwise, if the ABI is included in the library name, use the following:

 for (abi, ANDROID_ABIS): ANDROID_EXTRA_LIBS += $$PWD/library_name_$${abi}.so

ANDROID_EXTRA_PLUGINS

Specifies a path to C++ plugins or resources that your application has to bundle but that cannot be delivered through the assets system, such as QML plugins. With this variable, androiddeployqt will make sure everything is packaged and deployed properly.

ANDROID_EXTRA_PLUGINS must point to the directory where the extra plugin(s) are built. In addition, the build directory structure must follow a naming convention similar to Qt plugins, that is, plugins/<plugin name>.

The plugins libraries should have the name format libplugins_<type>_<name>_<abi>.so. To achieve that the plugin pro file could be defined as follows:

 TEMPLATE = lib
 CONFIG += plugin

 PLUGIN_TYPE = imageformats
 DESTDIR = $$top_builddir/plugins/myplugin
 TARGET = $$qt5LibraryTarget(myplugin, "plugins/$$PLUGIN_TYPE/")

with top_builddir defined in .qmake.conf as:

 top_builddir=$$shadowed($$PWD)

This will ensure that the correct name mangling is applied to the plugin library (plugins/myplugin/libplugins_imageformats_myplugin_armeabi-v7a.so).

Then, assuming an extra image format plugin myplugin is built as $$DESTDIR/plugins/myplugin/, the following ensures it is packaged correctly:

 ANDROID_EXTRA_PLUGINS += $$top_builddir/plugins

ANDROID_FEATURES

Specifies a module's features list:

 ANDROID_FEATURES += android.hardware.location.gps

For more information, see Android <uses-feature> Docs.

ANDROID_LIB_DEPENDENCIES

This is useful when writing a Qt module. It specifies a list of pre-built dependencies used by the module, for example:

 ANDROID_LIB_DEPENDENCIES += \
     plugins/libplugins_platforms_qtforandroid.so

ANDROID_MIN_SDK_VERSION

Specifies the minimum Android API level for the project. By default, this variable is set to API level 23.

ANDROID_PACKAGE_SOURCE_DIR

Specifies the path for a custom Android package template. The Android package template contains:

• AndroidManifest.xml file
• build.gradle file and other Gradle scripts
• res/values/libs.xml file

The path specified by this variable can contain custom Java classes under src directory. By default, the androiddeployqt tool copies the application template from the Qt for Android installation path into your project's build directory, then it copies the contents of the path specified by this variable on top of that, overwriting any existing files. For instance, you can make a custom AndroidManifest.xml for your application, then place this directly into the directory specified by this variable.

ANDROID_PERMISSIONS

Specifies a module's permissions list:

 ANDROID_PERMISSIONS += android.permission.ACCESS_FINE_LOCATION

For more information, see Android <uses-permission> Docs.

ANDROID_TARGET_SDK_VERSION

Specifies the target Android API level for the project. By default, this variable is set to API level 34.

ANDROID_VERSION_CODE

Specifies the application's version number. For more information, see Android App Versioning.

ANDROID_VERSION_NAME

Specifies the application's version in as a human readable string. For more information, see Android App Versioning.

CONFIG

Specifies project configuration and compiler options. The values are recognized internally by qmake and have special meaning.

The following CONFIG values control compiler and linker flags:

When you use the debug_and_release option (which is the default under Windows), the project will be processed three times: one time to produce a "meta" Makefile, and two more times to produce a Makefile.Debug and a Makefile.Release.

During the latter passes, build_pass and the respective debug or release option is appended to CONFIG. This makes it possible to perform build-specific tasks. For example:

 build_pass:CONFIG(debug, debug|release) {
     unix: TARGET = $$join(TARGET,,,_debug)
     else: TARGET = $$join(TARGET,,,d)
 }

As an alternative to manually writing build type conditionals, some variables offer build-specific variants, for example QMAKE_LFLAGS_RELEASE in addition to the general QMAKE_LFLAGS. These should be used when available.

The meta Makefile makes the sub-builds invokable via the debug and release targets, and a combined build via the all target. When the build_all CONFIG option is used, the combined build is the default. Otherwise, the last specified CONFIG option from the set (debug, release) determines the default. In this case, you can explicitly invoke the all target to build both configurations at once:

 make all

When linking a library, qmake relies on the underlying platform to know what other libraries this library links against. However, if linking statically, qmake will not get this information unless we use the following CONFIG options:

The following options define the application or library type:

These options define specific features on Windows only:

See Platform Notes for more information about the options for embedding manifest files.

The following options take an effect only on macOS:

The build process for bundles is also influenced by the contents of the QMAKE_BUNDLE_DATA variable.

The following options take an effect only on Linux/Unix platforms:

The CONFIG variable will also be checked when resolving scopes. You may assign anything to this variable.

For example:

 CONFIG += console newstuff
 ...
 newstuff {
     SOURCES += new.cpp
     HEADERS += new.h
 }

DEFINES

qmake adds the values of this variable as compiler C preprocessor macros (-D option).

For example:

 DEFINES += USE_MY_STUFF

DEFINES_DEBUG

Specifies preprocessor defines for the debug configuration. The values of this variable get added to DEFINES after the project is loaded. This variable is typically set in qmake.conf and rarely needs to be modified.

This variable was introduced in Qt 5.13.2.

DEFINES_RELEASE

Specifies preprocessor defines for the release configuration. The values of this variable get added to DEFINES after the project is loaded. This variable is typically set in qmake.conf and rarely needs to be modified.

This variable was introduced in Qt 5.13.2.

DEF_FILE

Specifies a .def file to be included in the project.

DEPENDPATH

Specifies a list of directories for qmake to scan, to resolve dependencies. This variable is used when qmake crawls through the header files that you #include in your source code.

DESTDIR

Specifies where to put the target file.

For example:

 DESTDIR = ../../lib

DISTFILES

Specifies a list of files to be included in the dist target. This feature is supported by UnixMake specs only.

For example:

 DISTFILES += ../program.txt

DLLDESTDIR

Specifies where to copy the target dll.

EXTRA_TRANSLATIONS

Specifies a list of translation (.ts) files that contain translations of the user interface text into non-native languages.

In contrast to TRANSLATIONS, translation files in EXTRA_TRANSLATIONS will be processed only by lrelease, not lupdate.

You can use CONFIG += lrelease to automatically compile the files during the build, and CONFIG += lrelease embed_translations to make them available in The Qt Resource System.

See the Qt Linguist Manual for more information about internationalization (i18n) and localization (l10n) with Qt.

FORMS

Specifies the UI files (see Qt Designer Manual) to be processed by uic before compiling. All dependencies, headers and source files required to build these UI files will automatically be added to the project.

For example:

 FORMS = mydialog.ui \
     mywidget.ui \
         myconfig.ui

GUID

Specifies the GUID that is set inside a .vcproj file. The GUID is usually randomly determined. However, should you require a fixed GUID, it can be set using this variable.

This variable is specific to .vcproj files only; it is ignored otherwise.

HEADERS

Defines the header files for the project.

qmake automatically detects whether moc is required by the classes in the headers, and adds the appropriate dependencies and files to the project for generating and linking the moc files.

For example:

 HEADERS = myclass.h \
           login.h \
           mainwindow.h

See also SOURCES.

ICON

This variable is used only on Mac OS to set the application icon. Please see the application icon documentation for more information.

IDLSOURCES

This variable is used only on Windows for the Visual Studio project generation to put the specified files in the Generated Files folder.

INCLUDEPATH

Specifies the #include directories which should be searched when compiling the project.

For example:

 INCLUDEPATH = c:/msdev/include d:/stl/include

To specify a path containing spaces, quote the path using the technique described in Whitespace.

 win32:INCLUDEPATH += "C:/mylibs/extra headers"
 unix:INCLUDEPATH += "/home/user/extra headers"

INSTALLS

Specifies a list of resources that will be installed when make install or a similar installation procedure is executed. Each item in the list is typically defined with attributes that provide information about where it will be installed.

For example, the following target.path definition describes where the build target will be installed, and the INSTALLS assignment adds the build target to the list of existing resources to be installed:

 target.path += $$[QT_INSTALL_PLUGINS]/imageformats
 INSTALLS += target

INSTALLS has a .CONFIG member that can take several values:

For more information, see Installing Files.

This variable is also used to specify which additional files will be deployed to embedded devices.

JAVA_HOME

Specifies the JDK/OpenJDK installation path used for building the project.

LEXIMPLS

Specifies a list of Lex implementation files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

LEXOBJECTS

Specifies the names of intermediate Lex object files. The value of this variable is typically handled by qmake and rarely needs to be modified.

LEXSOURCES

Specifies a list of Lex source files. All dependencies, headers and source files will automatically be added to the project for building these lex files.

For example:

 LEXSOURCES = lexer.l

LIBS

Specifies a list of libraries to be linked into the project. If you use the Unix -l (library) and -L (library path) flags, qmake handles the libraries correctly on Windows (that is, passes the full path of the library to the linker). The library must exist for qmake to find the directory where a -l lib is located.

For example:

 unix:LIBS += -L/usr/local/lib -lmath
 win32:LIBS += c:/mylibs/math.lib

To specify a path containing spaces, quote the path using the technique described in Whitespace.

 win32:LIBS += "C:/mylibs/extra libs/extra.lib"
 unix:LIBS += "-L/home/user/extra libs" -lextra

By default, the list of libraries stored in LIBS is reduced to a list of unique names before it is used. To change this behavior, add the no_lflags_merge option to the CONFIG variable:

 CONFIG += no_lflags_merge

LIBS_PRIVATE

Specifies a list of libraries to be linked privately into the project. The behavior of this variable is identical to LIBS, except that shared library projects built for Unix do not expose these dependencies in their link interface.

The effect of this is that if project C depends on library B which depends on library A privately, but C also wants to use symbols from A directly, it needs to link to A explicitly. Put differently, libraries linked privately are not exposed transitively at build time.

LITERAL_HASH

This variable is used whenever a literal hash character (#) is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application.

For example:

 # To include a literal hash character, use the $$LITERAL_HASH variable:
 urlPieces = http://doc.qt.io/qt-5/qtextdocument.html pageCount
 message($$join(urlPieces, $$LITERAL_HASH))

By using LITERAL_HASH in this way, the # character can be used to construct a URL for the message() function to print to the console.

MAKEFILE

Specifies the name of the generated Makefile. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

MAKEFILE_GENERATOR

Specifies the name of the Makefile generator to use when generating a Makefile. The value of this variable is typically handled internally by qmake and rarely needs to be modified.

MSVCPROJ_*

These variables are handled internally by qmake and should not be modified or utilized.

MOC_DIR

Specifies the directory where all intermediate moc files should be placed.

For example:

 unix:MOC_DIR = ../myproject/tmp
 win32:MOC_DIR = c:/myproject/tmp

OBJECTIVE_HEADERS

Defines the Objective-C++ header files for the project.

qmake automatically detects whether moc is required by the classes in the headers, and adds the appropriate dependencies and files to the project for generating and linking the moc files.

This is similar to the HEADERS variable, but will let the generated moc files be compiled with the Objective-C++ compiler.

See also OBJECTIVE_SOURCES.

OBJECTIVE_SOURCES

Specifies the names of all Objective-C/C++ source files in the project.

This variable is now obsolete, Objective-C/C++ files (.m and .mm) can be added to the SOURCES variable.

See also OBJECTIVE_HEADERS.

OBJECTS

This variable is automatically populated from the SOURCES variable. The extension of each source file is replaced by .o (Unix) or .obj (Win32). You can add objects to the list.

OBJECTS_DIR

Specifies the directory where all intermediate objects should be placed.

For example:

 unix:OBJECTS_DIR = ../myproject/tmp
 win32:OBJECTS_DIR = c:/myproject/tmp

POST_TARGETDEPS

Lists the libraries that the target depends on. Some backends, such as the generators for Visual Studio and Xcode project files, do not support this variable. Generally, this variable is supported internally by these build tools, and it is useful for explicitly listing dependent static libraries.

This list is placed after all builtin (and $$PRE_TARGETDEPS) dependencies.

PRE_TARGETDEPS

Lists libraries that the target depends on. Some backends, such as the generators for Visual Studio and Xcode project files, do not support this variable. Generally, this variable is supported internally by these build tools, and it is useful for explicitly listing dependent static libraries.

This list is placed before all builtin dependencies.

PRECOMPILED_HEADER

Indicates the header file for creating a precompiled header file, to increase the compilation speed of a project. Precompiled headers are currently only supported on some platforms (Windows - all MSVC project types, Apple - Xcode, Makefile, Unix - gcc 3.3 and up).

PWD

Specifies the full path leading to the directory containing the current file being parsed. This can be useful to refer to files within the source tree when writing project files to support shadow builds.

See also _PRO_FILE_PWD_.

OUT_PWD

Specifies the full path leading to the directory where qmake places the generated Makefile.

QM_FILES_RESOURCE_PREFIX

Specifies the directory in the resource system where .qm files will be made available by CONFIG += embed_translations.

The default is :/i18n/.

QM_FILES_INSTALL_PATH

Specifies the target directory .qm files generated by CONFIG += lrelease will be installed to. Does not have any effect if CONFIG += embed_translations is set.

QML_IMPORT_PATH

This variable is only used by Qt Creator. If you have an extra module that is kept outside of your Qt installation, you can specify its path here.

See Qt Creator: Using QML Modules with Plugins for details.

QMLPATHS

Expects a list of import paths that point to root directories of trees of QML modules. For example, if you have a custom location for your QML modules, you can specify it here.

QMAKE

Specifies the name of the qmake program itself and is placed in generated Makefiles. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

QMAKESPEC

A system variable that contains the full path of the qmake configuration that is used when generating Makefiles. The value of this variable is automatically computed.

QMAKE_APPLE_DEVICE_ARCHS

Specifies a list of architectures to build for. By default, a project is built for the development machine's architecture. This variable allows to override the default and build for a different architecture or to create multi-architecture binaries.

This variable is usually specified on the command line or in the project file.

See Qt for macOS for more information.

QMAKE_AR_CMD

Specifies the command to execute when creating a shared library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

QMAKE_BUNDLE_DATA

Specifies the data that will be installed with a library bundle, and is often used to specify a collection of header files.

For example, the following lines add path/to/header_one.h and path/to/header_two.h to a group containing information about the headers supplied with the framework:

 FRAMEWORK_HEADERS.version = Versions
 FRAMEWORK_HEADERS.files = path/to/header_one.h path/to/header_two.h
 FRAMEWORK_HEADERS.path = Headers
 QMAKE_BUNDLE_DATA += FRAMEWORK_HEADERS

The last line adds the information about the headers to the collection of resources that will be installed with the library bundle.

Library bundles are created when the lib_bundle option is added to the CONFIG variable.

See Platform Notes for more information about creating library bundles.

A project can also use this variable to bundle application translation files. The exact syntax depends on whether the project is using Xcode's legacy build system or its new build system.

For example when the following project snippet is built using the legacy build system:

 translations_en.files = $$PWD/en.lproj/InfoPlist.strings
 translations_en.path = en.lproj
 QMAKE_BUNDLE_DATA += translations_en

Xcode will ignore the original location of InfoPlist.strings and the file will placed into the bundle Resources directory under the provided translations_en.path path, so Resources/en.lproj/InfoPlist.strings

With the new build system, the relative location of the file is preserved, which means the file will incorrectly be placed under Resources/en.lproj/en.lproj/InfoPlist.strings

To ensure correct file placement, the project can either move the original file not to be in a sub-directory or it can choose not to specify the translations_en.path variable.

 # Approach 1
 translations_en.files = $$PWD/InfoPlist.strings
 translations_en.path = en.lproj

 # Approach 2
 translations_de.files = $$PWD/de.lproj/InfoPlist.strings

 QMAKE_BUNDLE_DATA += translations_en translations_de

See QTBUG-98417 for more details on how the Xcode build system changed its behavior in bundling translation files.

QMAKE_BUNDLE_EXTENSION

Specifies the extension to be used for library bundles. This allows frameworks to be created with custom extensions instead of the standard .framework directory name extension.

For example, the following definition will result in a framework with the .myframework extension:

 QMAKE_BUNDLE_EXTENSION = .myframework

QMAKE_CC

Specifies the C compiler that will be used when building projects containing C source code. Only the file name of the compiler executable needs to be specified as long as it is on a path contained in the PATH variable when the Makefile is processed.

QMAKE_CFLAGS

Specifies the C compiler flags for building a project. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. The flags specific to debug and release modes can be adjusted by modifying the QMAKE_CFLAGS_DEBUG and QMAKE_CFLAGS_RELEASE variables, respectively.

QMAKE_CFLAGS_DEBUG

Specifies the C compiler flags for debug builds. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

Specifies the C++ compiler that will be used when building projects containing C++ source code. Only the file name of the compiler executable needs to be specified as long as it is on a path contained in the PATH variable when the Makefile is processed.

QMAKE_CXXFLAGS

Specifies the C++ compiler flags for building a project. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. The flags specific to debug and release modes can be adjusted by modifying the QMAKE_CXXFLAGS_DEBUG and QMAKE_CXXFLAGS_RELEASE variables, respectively.

QMAKE_CXXFLAGS_DEBUG

QMAKE_INCDIR_OPENVG

Specifies the location of OpenVG header files to be added to INCLUDEPATH when building a target with OpenVG support. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

If the OpenVG implementation uses EGL then QMAKE_INCDIR_EGL may also need to be set.

QMAKE_INCDIR_X11

Specifies the location of X11 header file paths to be added to INCLUDEPATH when building an X11 target. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

QMAKE_INFO_PLIST

Specifies the name of the property list file, .plist, you would like to include in your macOS, iOS, tvOS, and watchOS application bundle.

In the .plist file, you can define some variables which qmake will replace with the relevant values:

If building for iOS, and the .plist file contains the key NSPhotoLibraryUsageDescription, qmake will include an additional plugin to the build that adds photo access support (to, e.g., QFile/QFileDialog). See Info.plist documentation from Apple for more information regarding this key.

QMAKE_IOS_DEPLOYMENT_TARGET

Specifies the hard minimum version of iOS that the application supports.

For more information, see Expressing Supported iOS Versions.

QMAKE_IOS_LAUNCH_SCREEN

Specifies the launch screen that is used by the application. If this is not set then a default launch screen is used.

QMAKE_LFLAGS

Specifies a general set of flags that are passed to the linker. If you need to change the flags used for a particular platform or type of project, use one of the specialized variables for that purpose instead of this variable.

QMAKE_LFLAGS_CONSOLE

Specifies the linker flags for building console programs. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

QMAKE_LFLAGS_DEBUG

Specifies the linker flags for debug builds. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

 QMAKE_RESOURCE_FLAGS += -threshold 0 -compress 9

QMAKE_RPATHDIR

Specifies a list of library paths that are added to the executable at link time so that the paths will be preferentially searched at runtime.

When relative paths are specified, qmake will mangle them into a form understood by the dynamic linker to be relative to the location of the referring executable or library. This is supported only by some platforms (currently Linux and Darwin-based ones) and is detectable by checking whether QMAKE_REL_RPATH_BASE is set.

QMAKE_RPATHLINKDIR

Specifies a list of library paths for the static linker to search for implicit dependencies of shared libraries. For more information, see the manual page for ld(1).

QMAKE_RUN_CC

Specifies the individual rule needed to build an object. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

QMAKE_SONAME_PREFIX

If defined, the value of this variable is used as a path to be prepended to the built shared library's SONAME identifier. The SONAME is the identifier that the dynamic linker will later use to reference the library. In general, this reference may be a library name or full library path. On macOS, iOS, tvOS, and watchOS, the path may be specified relatively using the following placeholders:

In most cases, using @rpath is sufficient and recommended:

 # <project root>/project.pro
 QMAKE_SONAME_PREFIX = @rpath

However, the prefix may be also specified using different placeholders, or an absolute path, such as one of the following:

 # <project root>/project.pro
 QMAKE_SONAME_PREFIX = @executable_path/../Frameworks
 QMAKE_SONAME_PREFIX = @loader_path/Frameworks
 QMAKE_SONAME_PREFIX = /Library/Frameworks

For more information, see dyld documentation on dynamic library install names.

For more information, see Expressing Supported iOS Versions.

QML_IMPORT_MAJOR_VERSION

Specifies the major version to be used for automatically generated QML type registrations. For more information, see Defining QML Types from C++.

QML_IMPORT_MINOR_VERSION

When automatically registering QML types defined in C++, register an additional version of the module using this minor version. Generally, minor versions to be registered are inferred from the meta objects.

You can use this variable if the meta objects have not changed and you still want to import a QML module with a newer minor version number. For example, MyModule metaobjects are at 1.1 level, but you want to import the module as 1.3.

QML_IMPORT_VERSION

Specifies QML_IMPORT_MAJOR_VERSION and QML_IMPORT_MINOR_VERSION as a <major>.<minor> version string.

QML_IMPORT_NAME

Specifies the module name to be used for automatically generated QML type registrations. For more information, see Defining QML Types from C++.

QML_FOREIGN_METATYPES

Specifies further JSON files with metatypes to be considered when generating qmltypes files. Use this when external libraries provide types that are exposed to QML, either directly or as base types or properties of other types. Qt types will automatically be considered and don't have to be added here.

QT

Specifies the Qt modules that are used by your project. For the value to add for each module, see the module documentation.

At the C++ implementation level, using a Qt module makes its headers available for inclusion and causes it to be linked to the binary.

By default, QT contains core and gui, ensuring that standard GUI applications can be built without further configuration.

If you want to build a project without the Qt GUI module, you need to exclude the gui value with the "-=" operator. The following line will result in a minimal Qt project being built:

 QT -= gui # Only the core module is used.

If your project is a Qt Designer plugin, use the value uiplugin to specify that the project is to be built as a library, but with specific plugin support for Qt Designer. For more information, see Building and Installing the Plugin.

QTPLUGIN

Specifies a list of names of static Qt plugins that are to be linked with an application so that they are available as built-in resources.

qmake automatically adds the plugins that are typically needed by the used Qt modules (see QT). The defaults are tuned towards an optimal out-of-the-box experience. See Static Plugins for a list of available plugins, and ways to override the automatic linking.

This variable currently has no effect when linking against a shared/dynamic build of Qt, or when linking libraries. It may be used for deployment of dynamic plugins at a later time.

QT_VERSION

Contains the current version of Qt.

QT_MAJOR_VERSION

Contains the current major version of Qt.

QT_MINOR_VERSION

Contains the current minor version of Qt.

QT_PATCH_VERSION

Contains the current patch version of Qt.

RC_FILE

Windows only. Specifies the name of the Windows resource file (.rc) for the target. See Adding Windows Resource Files.

RC_CODEPAGE

Windows only. Specifies the codepage that should be specified in a generated .rc file. This is only utilized if the VERSION or RC_ICONS variable is set and the RC_FILE and RES_FILE variables are not set.

RC_DEFINES

Windows only. qmake adds the values of this variable as RC preprocessor macros (/d option). If this variable is not set, the DEFINES variable is used instead.

 RC_DEFINES += USE_MY_STUFF

RC_ICONS

Windows only. Specifies the icons that should be included into a generated .rc file. This is only utilized if the RC_FILE and RES_FILE variable are not set. More details about the generation of .rc files can be found in the Platform Notes.

RC_LANG

Windows only. Specifies the language that should be specified in a generated .rc file. This is only utilized if the VERSION or RC_ICONS variable is set and the RC_FILE and RES_FILE variables are not set.

RC_INCLUDEPATH

Specifies include paths that are passed to the Windows Resource Compiler.

RCC_DIR

Specifies the directory for Qt Resource Compiler output files.

For example:

 unix:RCC_DIR = ../myproject/resources
 win32:RCC_DIR = c:/myproject/resources

REQUIRES

Specifies a list of values that are evaluated as conditions. If any of the conditions is false, qmake skips this project (and its SUBDIRS) when building.

RESOURCES

Specifies the name of the resource collection files (qrc) for the target. For more information about the resource collection file, see The Qt Resource System.

RES_FILE

Windows only. Specifies the name of the Windows resource compiler's output file for this target. See RC_FILE and Adding Windows Resource Files.

The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

SOURCES

Specifies the names of all source files in the project.

For example:

 SOURCES = myclass.cpp \
       login.cpp \
       mainwindow.cpp

See also HEADERS.

SUBDIRS

This variable, when used with the subdirs template specifies the names of all subdirectories or project files that contain parts of the project that need to be built. Each subdirectory specified using this variable must contain its own project file.

It is recommended that the project file in each subdirectory has the same base name as the subdirectory itself, because that makes it possible to omit the file name. For example, if the subdirectory is called myapp, the project file in that directory should be called myapp.pro.

Alternatively, you can specify a relative path to a .pro file in any directory. It is strongly recommended that you specify only paths in the current project's parent directory or its subdirectories.

For example:

 SUBDIRS = kernel \
           tools \
           myapp

If you need to ensure that the subdirectories are built in a particular order, use the .depends modifier on the relevant SUBDIRS elements.

For example:

 SUBDIRS += my_executable my_library tests doc
 my_executable.depends = my_library
 tests.depends = my_executable

The configuration above ensures that my_library is built before my_executable and that my_executable is built before tests. However, doc can be built in parallel with the other subdirectories, thus speeding up the build process.

Beside defining the build order, it is possible to modify the default behavior of SUBDIRS by giving additional modifiers to SUBDIRS elements. Supported modifiers are:

For example, define two subdirectories, both of which reside in a different directory than the SUBDIRS value, and one of the subdirectories must be built before the other:

 SUBDIRS += my_executable my_library
 my_executable.subdir = app
 my_executable.depends = my_library
 my_library.subdir = lib

TARGET

Specifies the name of the target file. Contains the base name of the project file by default.

For example:

 TEMPLATE = app
 TARGET = myapp
 SOURCES = main.cpp

The project file above would produce an executable named myapp on unix and myapp.exe on Windows.

TARGET_EXT

Specifies the extension of TARGET. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

TARGET_x

Specifies the extension of TARGET with a major version number. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

TARGET_x.y.z

Specifies the extension of TARGET with a version number. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

TEMPLATE

Specifies the name of the template to use when generating the project. The allowed values are:

For example:

 TEMPLATE = lib
 SOURCES = main.cpp
 TARGET = mylib

The template can be overridden by specifying a new template type with the -t command line option. This overrides the template type after the .pro file has been processed. With .pro files that use the template type to determine how the project is built, it is necessary to declare TEMPLATE on the command line rather than use the -t option.

TRANSLATIONS

Specifies a list of translation (.ts) files that contain translations of the user interface text into non-native languages.

Translation files in TRANSLATIONS will be processed by both lrelease and Using lupdate tools. Use EXTRA_TRANSLATIONS if you want only lrelease to process a file.

You can use CONFIG += lrelease to automatically compile the files during the build, and CONFIG += lrelease embed_translations to make them available in The Qt Resource System.

See the Qt Linguist Manual for more information about internationalization (i18n) and localization (l10n) with Qt.

TR_EXCLUDE

Specifies a list of paths (source files, subdirectories, and C++ include paths) to be excluded from handling in lupdate. The paths may contain wildcards. Relative paths are considered to be relative to _PRO_FILE_PWD_.

For example, to exclude source files:

 SOURCES += main.cpp \
     excluded.cpp \
     3rdparty/sqlite3.h \
     3rdparty/sqlite3.c
 TR_EXCLUDE += excluded.cpp 3rdparty/*

To exclude subdirectories of a SUBDIRS project:

 SUBDIRS += \
     libs \
     apps \
     tests
 TR_EXCLUDE += tests

To speed up lupdate's C++ parser, exclude include paths:

 linux {
     TR_EXCLUDE += /usr/include/boost/*
 }

UI_DIR

Specifies the directory where all intermediate files from uic should be placed.

For example:

 unix:UI_DIR = ../myproject/ui
 win32:UI_DIR = c:/myproject/ui

VERSION

Specifies the version number of the application if the app template is specified or the version number of the library if the lib template is specified.

On Windows, triggers auto-generation of an .rc file if the RC_FILE and RES_FILE variables are not set. The generated .rc file will have the FILEVERSION and PRODUCTVERSION entries filled with major, minor, patch level, and build number. Each number must be in the range from 0 to 65535. More details about the generation of .rc files can be found in the Platform Notes.

For example:

 win32:VERSION = 1.2.3.4 # major.minor.patch.build
 else:VERSION = 1.2.3    # major.minor.patch

VERSION_PE_HEADER

Windows only. Specifies the version number, that the Windows linker puts into the header of the .exe or .dll file via the /VERSION option. Only a major and minor version may be specified. If VERSION_PE_HEADER is not set, it falls back to the major and minor version from VERSION (if set).

 VERSION_PE_HEADER = 1.2

VER_MAJ

Specifies the major version number of the library if the lib template is specified.

VER_MIN

Specifies the minor version number of the library if the lib template is specified.

VER_PAT

Specifies the patch version number of the library if the lib template is specified.

VPATH

Tells qmake where to search for files it cannot open. For example, if qmake looks for SOURCES and finds an entry that it cannot open, it looks through the entire VPATH list to see if it can find the file on its own.

See also DEPENDPATH.

WINDOWS_TARGET_PLATFORM_VERSION

Specifies the targeted Windows version; this corresponds to the tag WindowsTargetPlatformVersion in vcxproj files.

On desktop Windows, the default value is the value of the environment variable WindowsSDKVersion.

WINDOWS_TARGET_PLATFORM_MIN_VERSION

Specifies the minimum version of the Windows target platform; this corresponds to the tag WindowsTargetPlatformMinVersion in vcxproj files.

Defaults to WINDOWS_TARGET_PLATFORM_VERSION.

YACCSOURCES

Specifies a list of Yacc source files to be included in the project. All dependencies, headers and source files will automatically be included in the project.

For example:

 YACCSOURCES = moc.y

_PRO_FILE_

Contains the path to the project file in use.

For example, the following line causes the location of the project file to be written to the console:

 message($$_PRO_FILE_)

_PRO_FILE_PWD_

Contains the path to the directory containing the project file in use.

For example, the following line causes the location of the directory containing the project file to be written to the console:

 message($$_PRO_FILE_PWD_)
