Dear experienced CMake coders!

I’m novice in writing CMake scripts…

Now I’m writng a `CMakeLists . txt` for a Fortran project with HDF5, MPI and OpenMP options (either shared and statically linked). The Fortran compilers in main use are GNU gfortran and Intel ifx.

And I’m having a difficulty in doing static linking with Intel ifx (which contains both MPI and OpenMP as internal libraries):

- Either one of the libraries (HDF5, MPI, or OpenMP) can be statically linked
- In cases of HDF5+MPI and OpenMP+MPI, they can be statically linked, but
- For HDF5+OpenMP(+MPI), some intel libraries (e.g. libirng) remain as shared libraries, even though the options `-static-intel -static-libgcc` are passed in `CMAKE_EXE_LINKER_FLAGS`.

Could some give me some suggestions on the cause of the problem and how to correct the issue?

By `--trace-expand`ing the CMake configuration process of a simple Fortran program which uses both HDF5 and OpenMP, I noticed lines with`-Bstatic -lirng -Bdynamic`, but the library seems not to be processed as a static library:

It seems to me that the match for `search_static` is limited to GNU ones (`gfortran`,`quadmath`, `stdc++`). Is my observation correct? If so, isn’t it insufficient? Is it related to the problem above?

The version of CMake I use is 3.31.10 (on Fedora linux).

Thanks in advance.
