add autotools build system

[jeffhammond]

Some users and packagers may prefer autotools to cmake.

[stefanhusmann]

Yes, especially if the given cmake build system is broken. It does not honor DESTDIR settings.

@stefanhusmann This appears to be due to ExternalProject_Add requiring DESTDIR to be manually propagated. This should be a one-liner for ParMETIS, METIS, and LAPACK since those external projects use CMake. But OpenBLAS and BLIS may require more care.

@stefanhusmann Did you export DESTDIR as an environment variable before running cmake? If so, would you mind opening an issue for this particular problem?

[stefanhusmann]

I only passed DESTDIR to the make command, not to the cmake command, and not exported. I will check and report back.
