To compile it you have to adapt the architecture file in cp2k/arch. Executing cp2k/tools/get_arch_name you can see your architecture, changing the environment variable FORT_C_NAME you can change the compiler on some architectures.

As make you should use the gnu make, and the architecture can be changed also with make ARCH=my_arch_name.

The kind of build (sdbg, sopt, pdbg, popt) can be changed with VERSION=build_type (actually using the build type as target also works). Targets can be: build, lib, clean, realclean, distclean.
