CMAKE_PREFIX_PATH

Semicolon-separated list of directories specifying installation prefixes to be searched by the find_package(), find_program(), find_library(), find_file(), and find_path() commands. Each command will add appropriate subdirectories (like bin, lib, or include) as specified in its own documentation.

By default this is empty. It is intended to be set by the project.

There is also an environment variable CMAKE_PREFIX_PATH, which is used as an additional list of search prefixes.

See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH, and CMAKE_IGNORE_PATH.
