Thank you to all of you for your help. It turned out that OpenKIM does some magic in the API package to make CMake remember what compilers were used to build the API, and then use the same for the models. That somehow goes wrong in an EasyBuild environment.
In the end, the solution was simply to add these lines to the easyconfig of the models: configopts += '-DCMAKE_C_COMPILER=`which icc` ' configopts += '-DCMAKE_CXX_COMPILER=`which icpc` ' configopts += '-DCMAKE_Fortran_COMPILER=`which ifort` ‘ I have updated my OpenKIM PR #7569 to reflect this. https://github.com/easybuilders/easybuild-easyconfigs/pull/7569 Thanks again for your help.
