Brad King ffc06c1239 Teach find_(library|file|path) to get prefixes from PATH (#15370)
The find_package command already knows how to compute installation
prefixes from PATH.  Use the same approach to establish prefixes for
find_library, find_file, and find_path to use to look in directories
like "<prefix>/lib[/<arch>]" and "<prefix>/include" for libraries and
headers.  This will reduce the amount of configuration end users need to
do to establish a work environment rooted under a specific prefix.
