-
-  This option is only meaningful if the --with-ft option is also used
-  to active Open MPI's fault tolerance behavior.
-
---with-blcr-libdir=<directory>
-  Look in directory for the BLCR libraries.  By default, Open MPI will
-  look in <blcr directory>/lib and <blcr directory>/lib64, which

-  Specify the directory where the Distributed MultiThreaded
