This one is hard to test until we start to merge things, but we'll want to remember to move this line:

scr/dist/CMakeLists.txt

Line 274 in d153d58

scr/src/axl_mpi.c

Nice catch! I mistakenly left that in. I also need to modify the dist script to include MPI=On when building AXL (if needed). Let me change that now

@adammoody, for dist, do I need to create both a noMPI library in addition to one with MPI enabled (similar to what is being done for other libraries like redset and others?

Yeah, I was just looking at that. I think we will need to create a noMPI section for AXL, since we use AXL in the serial executables, which should not have MPI. Maybe just copy the kvtree pattern again.

This should be easier to test when we merge the AXL PR.
