--------------------
* The Intel oneAPI NextGen LLVM compilers are now supported with
compiler id ``IntelLLVM``:
* The ``icx``/``icpx`` C/C++ compilers on Linux, and the ``icx``
C/C++ compiler on Windows, are fully supported as of oneAPI 2021.1.
* The ``ifx`` Fortran compiler on Linux is partially supported.
As of oneAPI 2021.1, ``ifx`` does not define several identification
macros, so CMake identifies it as the classic ``Intel`` compiler.
This works in many cases because ``ifx`` accepts the same command line
parameters as ``ifort``.
* The ``ifx`` Fortran compiler on Windows is not yet supported.
The Intel oneAPI Classic compilers (``icc``, ``icpc``, and ``ifort``)
continue to be supported with compiler id ``Intel``.
