"""This is the same as the oneAPI compiler but uses dpcpp instead of
icpx (for DPC++ source files). It explicitly refers to dpcpp, so that
CMake test files which check the compiler name (e.g. CMAKE_CXX_COMPILER)
detect it as dpcpp.
Ideally we could switch out icpx for dpcpp where needed in the oneAPI
compiler definition, but two things are needed for that: (a) a way to
tell the compiler that it should be using dpcpp and (b) a way to
customize the link_paths
