find-command-prefix-from-PATH-windows-only
------------------------------------------
* The :command:`find_library`, :command:`find_path`, and :command:`find_file`
commands no longer search in installation prefixes derived from the ``PATH``
environment variable on non-Windows platforms. This behavior was added in
CMake 3.3 to support Windows hosts but has proven problematic on UNIX hosts.
Users that keep some ``<prefix>/bin`` directories in the ``PATH`` just for
their tools do not necessarily want any supporting ``<prefix>/lib``
directories searched. One may set the ``CMAKE_PREFIX_PATH`` environment
variable with a :ref:`;-list <CMake Language Lists>` of prefixes that are
to be searched.
