• Check for MPI and Parallel HDF5, if available build with -DLATTE_BUILD_MPI=ON

Hi,

I was trying to build latte, but got stuck while pulling ParallelAccelerator. As mentioned in setup instructions, when I issue the command Pkg.checkout("ParallelAccelerator"), it dumps the following error:

INFO: Checking out ParallelAccelerator master...
ERROR: ParallelAccelerator is dirty, bailing

I am using Julia 0.5, Ubuntu 14.04

I followed the procedure mentioned in http://intellabs.github.io/Latte.jl/latest/setup/ for setting up Latte.
However, the last step to test if everything was installed properly
julia> Pkg.test("Latte") is failing.

Below is the error message:

julia> Pkg.test("Latte")

Any help in this direction is appreciated.

CMake has a lot of issues finding mpi wrapper. Latte should probably just check for CC (Cray wrapper), mpiicpc (Intel MPI), and mpic++ (MPICH).
