# MPI
|
||
|
|
|
||
|
|
To add MPI, like OpenMP, you'll be best off with CMake 3.9+.
|
||
|
|
|
||
|
|
```cmake
|
||
|
|
find_package(MPI REQUIRED)
|
||
|
|
message(STATUS "Run: ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS} ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS")
|
||
|
|
target_link_libraries(MyTarget PUBLIC MPI::MPI_CXX)
|
||
|
|
```
|
||
|
|
|
||
|
|
However, you can imitate this on CMake 3.1+ with:
|
||
|
|
|
||
|
|
```cmake
|
||
|
|
find_package(MPI REQUIRED)
|
||
|
|
|
||
|
|
# For supporting CMake < 3.9:
|
||
|
|
|
||
|
|
if(NOT TARGET MPI::MPI_CXX)
|
||
|
|
add_library(MPI::MPI_CXX IMPORTED INTERFACE)
|
||
|
|
|
||
|
|
set_property(TARGET MPI::MPI_CXX
|
||
|
|
PROPERTY INTERFACE_COMPILE_OPTIONS ${MPI_CXX_COMPILE_FLAGS})
|
||
|
|
set_property(TARGET MPI::MPI_CXX
|
||
|
|
PROPERTY INTERFACE_INCLUDE_DIRECTORIES "${MPI_CXX_INCLUDE_PATH}")
|
||
|
|
set_property(TARGET MPI::MPI_CXX
|
||
|
|
PROPERTY INTERFACE_LINK_LIBRARIES ${MPI_CXX_LINK_FLAGS} ${MPI_CXX_LIBRARIES})
|
||
|
|
endif()
|
||
|
|
|
||
|
|
message(STATUS "Run: ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS} ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS")
|
||
|
|
target_link_libraries(MyTarget PUBLIC MPI::MPI_CXX)
|
||
|
|
|
||
|
|
```
