FindBoost: Search next to MPI libraries for boost_mpi (#14739) |
|
|
|
Some distributions place boost_mpi next to the MPI libraries against |
|
which it was built instead of next to the other Boost libraries. If |
|
find_package(MPI) has already been run prior to find_package(Boost) then |
|
MPI_CXX_LIBRARIES or MPI_C_LIBRARIES may be set to the location of the |
|
MPI libraries. Teach FindBoost.cmake to look there for boost_mpi and |
|
boost_mpi_python after looking next to the other Boost libraries but |
|
not consider the location to be Boost_LIBRARY_DIR. |
