Kurt Kartaltepe d928bfd1ea cmake: Fix warnings and normalize variables/errors
As of 3.17 using find_package_handle_standard_args checks that the name
of the FindXXX file and the first argument are the same case.

Some modules used non-standard variables or the old singular variables
instead of plurals. This normalizes variable usage to the new-style.

Some CMakeLists.txt did custom error checking instead of propagating
find_package errors. These were changes to call find_package with
REQUIRED or without QUIET where needed and shortens the custom status
messages. This helps users who want to enable that functionality see
what precisely wasnt found.
