CMAKE_PREFIX_PATH

;-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.

По умолчанию это пустое значение. Оно должно устанавливаться проектом.
