Since commitffc06c1239(Teach find_(library|file|path) to get prefixes from PATH, 2015-02-18, v3.3.0-rc1~430^2) we search in `<prefix>/include` and `<prefix>/lib` directories for prefixes with `bin` directories in the `PATH` environment variable. The motivation was to search the installation prefixes of MSYS and MinGW development environments automatically. This behavior can search undesired prefixes that happen to be in the `PATH` for unrelated reasons. It was reverted for non-Windows hosts within a year by commitb30b32a493(Drop find_(library|file|path) prefixes from PATH on non-Windows, 2016-05-09, v3.6.0-rc1~82^2) but was kept on Windows hosts to support its motivating use case. However, similar problems have since been observed on Windows. For example, commit955d6245c1(MSVC: Revert "Teach find_library to consider the 'libfoo.a' naming convention", 2022-11-28, v3.25.1~6^2) was primarily due to undesired discovery of libraries in `PATH`-derived prefixes. Since commit5e5132e1b1(MinGW: Search for packages in standard MSYSTEM environment prefixes, 2023-09-11) we search MSYS and MinGW environments' prefixes explicitly, so `PATH`-derived prefixes are no longer needed for the original motivating use case. Fixes: #24216

When more than one value is given to the ``NAMES`` option this command by
|
|
default will consider one name at a time and search every directory
|
|
for it. The ``NAMES_PER_DIR`` option tells this command to consider one
|
|
directory at a time and search for all names in it.
