Error thrown when trying to build ExaTn using Intel compilers.

[cameton]

Trying to run cmake for ExaTn using Intel's C/C++/Fortran compilers indicates that they are unsupported, then throws an error.

[DmitryLyakh]

This CMAKE error comes from CPP Microservices submodule, which apparently does not officially support the Intel compiler suite. But we cant try simply removing that CMAKE check to see if CPP Microservices will work fine when built with the Intel C++ compiler.

[DmitryLyakh]

Can you try commenting the three lines in CMake at tpls/cppmicroservices/CMakeLists.txt, starting at line 111?

[cameton]

Your suggestion allows the CMake step to succeed, but it seems to introduce a number of warnings and an error using make install.

These warnings are thrown repeatedly:
