I tried BCP with mpi1, but it should work just fine with mpi2.

--with-mpi-incdir=/path/to/the/dir/where/the/mpi/headers/are
--with-mpi-lib="/path/to/mpi/libraries/libmpich.a"

Note the difference: for incdir you must specify the directory, for lib you
must specify the library file. Also, you may need to specify more than one
lib. In that case you still must specify only one --with-mpi-lib, but
stick all libs within the quotes. E.g., on BlueGene I need to use:
--with-mpi-lib="-L/bgl/BlueLight/ppcfloor/bglsys/lib -lmpich.rts -lmsglayer.rts -ldevices.rts -lrts.rts"

The easiest is if after configuring BCP you look at Bcp/examples and check out
the Makefiles there.
