Given that you have a foobar that identifies itself as 1.2.3 from now on a
find_package(foobar 1.2 EXACT)
will succeed, as 1.2.3 will now be considered as being 1.2. Until now this was
only the case for version 1.2.0.
Move the Tests/FPHSA_InvalidFOUND_VAR test case over to a new
RunCMake.FPHSA test with a BadFoundVar case. The RunCMake tests are
built to cover failure cases easily and robustly.
