Deprecated flags:
* BUILD_DEBUG. This was redundant since CMake also has such flag. The build type can now be switched by passing -DCMAKE_BUILD_TYPE=<Release|Debug|RelWithDebugInfo|...> to cmake. See CMake documentation on CMAKE_BUILD_TYPE on all av
* BUILD_UTILS. The utility library is now always built along the core library. We can reintroduce this flag if needed when the library grows larger. Currently MPI functions depend on Utils and without the flag we don't have to worr
* BUILD_RT_VISUALIZATION. RT visualization has been dormant for a while and I'm not even sure if it works any more. Eventually the RT library should be generalized and moved to Utils at some point. Disabled the build flag for the t
