# CMAKE_PREFIX_PATH

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

The `CMAKE_PREFIX_PATH` environment variable may be set to a 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.

This variable may hold a single prefix or a list of prefixes separated by `:` on UNIX or `;` on Windows (the same as the `PATH` environment variable convention on those platforms).

See also the `CMAKE_PREFIX_PATH` CMake variable.
