Failed to generate makefiles (intel-qs) - c++

Question

https://github.com/iqusoft/intel-qs/issues/32#issue-708056939
I downloaded the relevant package and ran the instructions as shown in the document until I got an error at this step.
CXX=mpiicpc cmake -DIqsMPI=ON -DIqsUtest=ON ..
Then it reported an error
root#vm:~/intel-qs/build# CXX=mpiicpc cmake -DIqsMPI=ON -DIqsUtest=ON ..
-- The CXX compiler identification is unknown
-- Check for working CXX compiler: /opt/intel/compilers_and_libraries_2020.2.254/linux/mpi/intel64/bin/mpiicpc

CMake Error at /opt/cmake-3.12.2/share/cmake-3.12/Modules/CMakeTestCXXCompiler.cmake:45 (message):
The C++ compiler

It fails with the following output:

If anyone knows how to do it, it would be greatly appreciated.
