CMake for tests in its own folder

Besides making it more simple to add a new test now since
you don't need to play hide and seek with the main cmake
this has another good thing: on IDE's that scan the cmake
to create targets on the project tree, the main project
was being popullated with test-targets on the main tree
and not inside the tests directory.
