- find-windows-no-PATH-prefixes
- -----------------------------
- * The :command:`find_library`, :command:`find_path`, and :command:`find_file`
- commands no longer search in installation prefixes derived from the ``PATH``
- environment variable. This behavior was added in CMake 3.3 to support
- MSYS and MinGW (``MSYSTEM``) development environments on Windows, but
- it can search undesired prefixes that happen to be in the ``PATH`` for
- unrelated reasons. Users that keep some ``<prefix>/bin`` directories in
- the ``PATH`` just for their tools do not necessarily want any corresponding
- ``<prefix>/lib`` or ``<prefix>/include`` directories searched.
- The behavior was reverted for non-Windows platforms by CMake 3.6.
- Now it has been reverted on Windows platforms too.
- One may set the ``CMAKE_PREFIX_PATH`` environment variable with a
- :ref:`semicolon-separated list <CMake Language Lists>` of prefixes
- that are to be searched.
