Re-thinking the build system to bring it more into line with the conventions.

We removed that implementation where the build directory isn't set up to build with exactly one
configuration of the project but potentially several variants: the same build directory
can/must be used for debug and release builds, for full or compact profile versions, etc.
So we reworked the CMakeLists, and now one build dir deal with exactly one configuration
of the project's libraries and tools.
