Libraries for intel/18.0.3 and intel/17.0.7 are not compatible with cxx17.
Intel compilers need gnu library to support 2017 ISO C++ standard, and cxx17 is the module to load the gnu environment for the intel compilers.
You could have errors when you try to compile with the libraries with the default intel environment.
