Possible incorrect build order when building FORTRAN interface

[mvsivaselvan]

I am building SUNDIALS 7.0.0 with BUILD_FORTRAN_MODULE_INTERFACE=ON.

I am using the Intel oneAPI C (icx) and FORTRAN (ifx) compilers on Windows.

It appears that the target sundials_fnvecmanyvector_mod is attemped to be built before the target sundials_fgeneric_mod although the former depends on the latter. During the attempted build of sundials_fnvecmanyvector_mod, I get the error below indicating that the modules fsundials_nvector_mod and fsundials_context_mod cannot be found. Both should be present if the sundials_fgeneric_mod had been built. I am not sure why this happens, because the CMakeLists.txt for sundials_fnvecmanyvector_mod has the dependency on sundials_fgeneric_mod.

Any suggestions would be much appreciated.

Can you confirm that this is with SUNDIALS v7.0.0 release candidate and not v6.7.0? The main branch is pointing at v6.7.0.

[mvsivaselvan]

Apologies, I had previously cloned the main branch.

I just cloned the v7.0.0-rc.1 tag and tried to build it. I got the exact same error.

What CMake generator are you using?

[mvsivaselvan]

I am using the Ninja CMake generator. I have also tried the Visual Studio 2022 generator with the same outcome.

This should be fixed by #506.
