For compiling with the Clang/LLVM compilers a CMake preset is
provided that can be loaded with
`-C ../cmake/presets/clang.cmake`. Similarly,
`-C ../cmake/presets/intel.cmake` should switch the compiler
toolchain to the Intel compilers.
toolchain to the Intel compilers and `-C ../cmake/presets/pgi.cmake`
should switch the compiler to the PGI compilers.
In addition you can set ``CMAKE_TUNE_FLAGS`` to specifically add
compiler flags to tune for optimal performance on given hosts. By
