Some of the feature flags are named differently and clwb is missing on
my i7-1065G7. cascadelake and cannonlake might have similar problems but
I do not have access to those architectures to test.

- add cuda variant, enabled by default, but conflicting with
  strumpack@:3.9.999
- add zfp variant, enabled by default, but conflicting with
  strumpack@:3.9.999
- update minimum CMake version to 3.11
- for version 4.0.0:, do not use mpi wrappers. v4.0.0 uses CMake
  MPI targets
- for version 4.0.0, add dependency on butterflypack@1.2.0:
- remove versions 3.1.0 and older
- make parmetis variant True by default
- add TODO for slate variant (spack package not ready yet)

While I believe there must have been a reason to restrict libtool to <=
2.4.2, adios compiles just fine with libtool 2.4.6 for me.

In fact, without this change, I'm getting this error:

libtool: Version mismatch error.  This is libtool 2.4.6, but the
libtool: definition of this LT_INIT comes from libtool 2.4.2.
libtool: You should recreate aclocal.m4 with macros from libtool 2.4.6

This doesn't make much sense, since spack did build libtool@2.4.2 as a
dependency, and was supposedly trying to use it. My guess is that on
this system (NERSC's cori) the system libtool in /usr/bin, which is
2.4.6 somehow got picked up partially.

Semi-recently the lua spackage was updated to explicitly add libtinfow
to the lua build line. Ncurses provides this but only when the +termlib
variant is enabled
