CMake Commands in Qt6 Protobuf
You should call the following CMake commands to use the Qt6::Protobuf module in your project:
find_package(Qt6 REQUIRED COMPONENTS Protobuf) target_link_libraries(mytarget PRIVATE Qt6::Protobuf)
You can use the qt_add_protobuf CMake command to implicitly call Qt Protobuf code generation for your project.
Using qt_add_protobuf
cmake_minimum_required(VERSION 3.16...3.22) project(MyThings) find_package(Qt6 REQUIRED COMPONENTS Protobuf) qt_standard_project_setup() qt_add_protobuf(MyMessages GENERATE_PACKAGE_SUBFOLDERS PROTO_FILES path/to/message.proto path/to/other_message.proto PROTO_INCLUDES /path/to/proto/include ) qt_add_executable(MyApp main.cpp) target_link_libraries(MyApp PRIVATE MyMessages)
In the example above, we generate a library called MyMessages
, which contains the message types defined in the paths passed to the PROTO_FILES
option. The GENERATE_PACKAGE_SUBFOLDERS
option to generate a folder structure for the generated files. And the PROTO_INCLUDES
option tells protoc to look for dependencies or imports in the specified directories. We create a target for an executable called MyApp
, which we link to the MyMessages
library.
