Error when using MKL as the math kernel lib.

[grysgreat]

Details

When I compiled the unit tests using mkl as a math library, the compiled program failed to execute successfully. The error is as follows:

./Perf_Hsolver_Kernels: error while loading shared libraries: libifcore.so.5: cannot open shared object file: No such file or directory

My compilation process is as follows:

1. Use an intel environment mirror in a bohrium cluster
2. source/opt/Intel/oneapi setvars. Sh, activate the Intel environment
3. Run the ./toolchain_intel.sh dependent installation script
4. Add the unit test compilation option in ./build_abacus_intel.sh
5. Run the ./build_abacus_intel.sh to compile abacus and unittest
6. Execute the compilation options I need.

Then the above error occurred.

Found that there are indeed many libraries not found, including a part of the mkl library.

@caic99, could you have a look?

Fix that. Make sure to load the MKL environment wherever MKL-codes is compiled and run.
