find_path no longer searches PATH on UNIX
The change in commit b30b32a4 regressed long-standing behavior of find_path
, find_file
, and find_library
of searching the entries in the PATH
itself in addition to reverting the derivation of prefixes from PATH
on non-Windows platforms. Ideally they should not search PATH
itself, but some of our find modules accidentally depend on this behavior. Therefore the change regressed these find modules.
We will have to restore the behavior and possibly later drop it in a compatible way using a policy.
