Restructure the cmake cuda process. Remove the policy and always set CMAKE_CUDA_ARCHITECTURE to 30, if not set. This will fail when someone is trying to build with cuda 10.2 or higher, as cuda 10.2 minimum support is 52.

NOTICE: preferred way is to set CMAKE_CUDA_ARCHITECTURE as cmake argument OR in the config file to the real gpu architecture. For example phoenix tesla P100 have the compute capability 60.

Update cmake to dev version.

Few refactorings in cmake. Remove the old openmp flag. Put the intel and gcc libraries in the compiler file.

Make use of the new cmake command: target_link_options, target_compile_options and target_compile_definitions.

Removed unused machine config files.
Removed CAB_COMPILER variable. compiler flag files is now loaded regarding the CMAKE_CXX_COMPILER_ID variable:
	https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_COMPILER_ID.html
Removed the 64 bit support.
