[CMake] Setting build type

[Adam Getchell]

Thanks for your reply.

I'm not sure I follow your answer. I do delete the directory each time I
build, but I'm still not understanding how you're building release or debug
versions to begin with.

I'm just automatically getting Release, unless I edit CMakeCache.txt after
I've built once.

I just checked CGAL_CreateSingleSourceCGALProgram.cmake which is invoked in
my CMakeLists.txt, but I do not see it setting the build type to Release.
