CMAKE_PREFIX_PATH

:ref:Semicolon-separated list <CMake Language Lists> of directories specifying installation prefixes to be searched by the :command:find_package, :command:find_program, :command:find_library, :command:find_file, and :command: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 :envvar:CMAKE_PREFIX_PATH, which is used as an additional list of search prefixes.

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