If you are happy with the # auto- detected configuration for your language, then you're done. If # not, you have two options: # # :: # # 1. Set MPI__COMPILER to the MPI wrapper (mpicc, etc.) of your # choice and reconfigure. FindMPI will attempt to determine all the # necessary variables using THAT compiler's compile and link flags. # 2. If this fails, or if your MPI implementation does not come with # a compiler wrapper, then set both MPI__LIBRARIES and # MPI__INCLUDE_PATH. You may also set any other variables # listed above, but these two are required. This will circumvent # autodetection entirely. # # When configuration is successful, MPI__COMPILER will be set to # the compiler wrapper for , if it was found. MPI__FOUND # and other variables above will be set if any MPI implementation was # found for , regardless of whether a compiler was found. # # When using MPIEXEC to execute MPI applications, you should typically # use all of the MPIEXEC flags as follows: # # :: # # ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS # ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS # # where PROCS is the number of processors on which to execute the # program, EXECUTABLE is the MPI program, and ARGS are the arguments to # pass to the MPI program. # add_library (yap_mpi SHARED ${MPI_SOURCES}) target_link_libraries(yap_mpi libYap ${MPI_LIBRARIES}) set_target_properties (yap_mpi PROPERTIES PREFIX "") include_directories (${MPI_INCLUDE_DIRS}) add_definitions (-DHAVE_MPI_H=1) install(TARGETS yap_mpi LIBRARY DESTINATION ${dlls} ) endif (MPI_C_FOUND)
