CMake can't do that. But if you need MPI, use
find_package(MPI REQUIRED)
include_directories(${MPI_INCLUDE_PATH})
add_executable(test1 test1.cxx)
add_executable(test2 test2.cxx)
target_link_libraries(test2 ${MPI_LIBRARIES})
set_target_properties(test2 PROPERTIES
COMPILE_FLAGS "${MPI_COMPILE_FLAGS}"
LINK_FLAGS "${MPI_LINK_FLAGS}")
