This is a test... I need to run it just like a normal test. I know
this sound weird to check for something that do not compile. The
simpliest case is when I need to trigger a static assert. Another
example could be for ITK to check that their itkConceptChecking are
actually working: Luis are you doing that ?

Or maybe I misunderstood you suggestion, and I could run the test, by
simply sending the stored result from CMakeCache.txt (thus the test
would be run at build time), is this correct ?

Thanks again,
