find_package: Test error and warning messages in failure cases
Add a "CMakeCommands.find_package" test to run CMake on a bunch of cases in which find_package fails. Check that the process return code and warning/error messages are as expected. Record expected test output in corresponding files for reference by the check. These files will also serve as a reference for the message text in each case.
