This commit overhauls the libMesh package script in a number of ways: * We now inherit from AutotoolsPackage. * libMesh contains about a dozen third-party dependencies that can only be provided by the copy bundled with libMesh. This patch enumerates all such bundled dependencies and disables all of them by default. * libMesh supports compilation with external installations of boost, eigen, hdf5, slepc, and tbb; this patch adds all of them to package.py. * libMesh will look for a few system executables (xz, bzip, gdb) by default. This is now disabled. * libMesh will now used a copy of perl installed by spack instead of trying to find the system copy. * Compilation with non-system MPI installations requires an additional flag (--with-mpi=); this has been added. |
