Build examples and tests only if their requirements are met

If the respective modules aren't available we cannot build the tests
and examples. We drop the qtConfig(opengl) requirement for the opengl
examples as
a, we would need to make the QtGui configuration available for that to
   work, and
b, we should not add too much detail to the tests and examples build
   configurations. Checking each test and example for every feature it
   uses would be too much.
