I really discourage using 'make install' - rdma-core is complicated
and adds a lot of files to the system. It is very hard to undo 'make
install'.

For most things just set LD_LIBRARY_PATH=build/lib and just forget
about installing

If you do have to install use the cbuild package builders and install
the RPMs. At least that can be undone.
