🐛 Describe the bug

When compiling the source code (tag 2.4.1) with USE_MPI=ON cmake throws the following error

CMake Error at cmake/public/utils.cmake:314 (add_executable):
  Cannot find source file:

    /users/mattmoll/sfw/pytorch/binaries/run_plan_mpi.cc

  Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm

CMake Error at cmake/public/utils.cmake:314 (add_executable):
  No SOURCES given to target: run_plan_mpi
Call Stack (most recent call first):
  binaries/CMakeLists.txt:39 (caffe2_binary_target)

The problem is lines 38-41 in binaries/CMakeLists.txt

if(USE_MPI)
  caffe2_binary_target("run_plan_mpi.cc")
  target_link_libraries(run_plan_mpi ${MPI_CXX_LIBRARIES})
endif()

since there is no such file in the checked out source code
