[CMake] CTest + Catch Framework

[Robert Dailey]

I believe so, but then you run into the chicken and egg problem:

I need to fully build all unit tests in order to know all the test
cases, but I need to define the tests at the generation phase (before
build).

I'm just not sure how to handle this. The best i can think of is to
generate 1 test executable per CPP file that we write in our unit
tests (generally 1 CPP file per class that is unit tested). Any ideas?
