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-libgccare passed inCMAKE_EXE_LINKER_FLAGS.
Could some give me some suggestions on the cause of the problem and how to correct the issue?
By --trace-expanding 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.

p.s. I attached the fragment of trace as an image to avoid "An error occurred: Sorry, new users can only put 2 links in a post.” error…
