Alternative Argobots installation path?

[devreal]

I am trying to give the Argobots integration (#6578) a shot but I am having trouble with the configuration process. I have installed Argobots through BOLT, say in $BOLTROOT in a subdirectory of $HOME). I configure the current Open MPI master using --with-threads=argobots. My first attempt failed because abt.h was not found. So I set C_INCLUDE_PATH=$BOLTROOT/include which gets me past that point but then fails with

checking for ABT_init in -labt... no

What is the recommended way to announce an alternative installation path for Argobots to Open MPI? I don't see anything helpful coming from configure --help. Maybe I'm missing the obvious?

It would seem like there should be a --with-argobots=DIR kind of option, similar to other optional packages.

That will come as a follow-on PR.
@devreal thanks for the interest in using argobots, but you may want to wait a while. There will need to be a libevent that is argobots aware before you can actually use argobots with Open MPI. The decision was made to go that direction rather than try to support libevent in open mpi by features in the argobot component in the original PR.
