Build issue on Julia 1.

[morrisonlevi]

I can't build MPI on Julia 1.1:

This is using GCC 7.3 and OpenMPI 3.1, though it doesn't look like it probably matters here.

I see the build bot using Julia 0.7. Is this simply not compatible with Julia 1.0+?

It looks like you don't have CMake installed. Try installing it and running ]build MPI.

[morrisonlevi]

I do have CMake installed, although I guess I didn't have it in PATH. Thanks!

Can the error be improved here, somehow? It was unclear to me which part of the command failed, so knowing it was cmake and not .. or some other piece would have helped me figure it out on my own.

[lcw]

I am happy to accept pull requests that provide better error messages for the build process!

[morrisonlevi]

Would that piece of code be part of the BinDeps package?

[lcw]

It is unclear to me how to catch the error using BinDeps.

Alternatively, we could try to avoid the error all together by using CMakeWrapper.jl which ensures that CMake is installed and provides a BinDeps.jl-compatible CMakeProcess class.

CMake will no longer be required in the next release (fixed by #271).
