It appears that MPI_<LANG>_VERSION is returning the version of the MPI _standard_ that is supported by the chosen MPI. While I am sure this is useful in some contexts, it’s actually not what I want/need for my project and it is quite inconsistent with analogous versions such as CMAKE_<LANG>_COMPILER_VERSION. E.g., CMAKE_Fortran_COMPILER_VERSION returns something like 18.0.3.xxxxx for my current Intel compiler whereas the Fortran language standard that it nominally supports is 2008.
Our project has dependencies on external libraries that in turn have dependencies on MPI. We would like to ensure that we choose the external library that was compiled with the same vendor version of MPI used in our project. In theory such information can be derived from MPI_<LANG>_LIBRARY_VERSION, but it is nontrivial and some conventions need to be established. The proper home for such logic is FindMPI.cmake. I would not think that we are the only project facing this frustration, but given that MPI_<LANG>_LIBRARY_VERSION is only in the very latest release of cmake, others must have found other means to compensate for this? -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
