Generating header tests by detecting headers

[EricWF]

Header tests are required to ensure that each header is self sufficient. It is also required to ensure that headers that arn't covered by unit tests don't have syntax errors. Currently header tests are manually written. They simple include a single headers.

Is it possible to create a CMake command to glob headers, generate the tests , and compile them? This would remove a ton of dumb files and make maintaining header tests almost zero work.
