| 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. |
