That is the CMake style; at the start of a test it tells what it is going to
do (e.g., "Check for working C compiler: gcc"), and at the end of the test
it gives the same message followed by the positive result (e.g., "-- works")
or the negative result (e.g., "-- broken") depending on the result of the
test.  See CMakeTestCCompiler.cmake for how this style is implemented for
the first question above. Actually, I think it is an excellent style.

Your second question about turning off the automatic C++ test for C-only
projects, I will leave to others more knowledgable than me.
