Can't find MPI

[TangLaoya]

Dear author,

Thank you very much for providing so powerful cmake file. I am trying to use it to generate visual studio 2022 project, I have installed the latest Intel oneapi 2024.1 and running the cmake, the following error displayed:

`
Could NOT find MPI_C (missing: MPI_C_LIB_NAMES MPI_C_HEADER_DIR MPI_C_WORKS)
Could NOT find MPI_Fortran (missing: MPI_Fortran_LIB_NAMES MPI_Fortran_F77_HEADER_DIR MPI_Fortran_MODULE_DIR MPI_Fortran_WORKS)
CMake Error at C:/Program Files/CMake/share/cmake-3.29/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
Could NOT find MPI (missing: MPI_C_FOUND MPI_Fortran_FOUND C Fortran)
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.29/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.29/Modules/FindMPI.cmake:1837 (find_package_handle_standard_args)
CMakeLists.txt:45 (find_package)

I have set the environment both I_MPI_ROOTandMPI_ROOTtoD:\Program Files (x86)\Intel\oneAPI\mpi\latest`

could you please help me to take a look at it?

Thanks,
Tang Laoya

Dear scivision,

This modification works for me. I juast added the following code at line 26:

set(ENV{Path} "$ENV{Path};$ENV{I_MPI_ROOT}/bin")

Thanks,

Hi Tang, FindMPI.cmake looks at ENV{I_MPI_ROOT} by default, so I'm not sure why this change was needed on your system.
