Help: Restore docs that find_library considers LIB, not INCLUDE (!5772) · Merge requests · CMake / CMake

Documentation updates in !3444 (merged) accidentally switched the find_library documentation to mention INCLUDE where it should be LIB.

While at it, update find_file and find_path to mention INCLUDE and PATH in the order they are considered.

Backport: release
