CMake >= 3.21, add MUMPS_ENABLE_RPATH for BUILD_SHARED_LIBS

• packaging bugfixes
• CMake >= 3.21 for *_IS_TOP_LEVEL helping robustness
• MUMPS_ENABLE_RPATH is often good to use if using BUILD_SHARED_LIBS (normally default static builds are easier to use)

rename project to mumps-superbuild

As noted to avoid naming confusion

MUMPS upstream v5.8.2

MUMPS 5.8.2 gives bugfixes--we didn't change the CMake script significantly.

improve linking robustness

restore ability to find METIS

fixes #125

MUMPS 5.8.1 upstream; MUMPS >= 5.2 upstream

MUMPS V5.8.1 upstream release incorporated

• internal quality improvements

• MUMPS >= 5.2 upstream supported--this is to simplify our scripts and make them easier to maintain

• Fix Intel oneAPI with intsize64=true

• METIS, ParMETIS, and/or Scotch are now built automatically if requested, including on Windows.

• Scalapack is built automatically if requested and not found (or MUMPS_find_SCALAPACK is false)

don't require download, work with oneAPI 2025.2

• Users can specify a local resource to avoid downloading MUMPS source like cmake -Bbuild -DMUMPS_url=/path/to/mumps.zip
• Intel oneAPI 2025.2 introduced breaking MKLconfig.cmake changes that are handled with this release

Fix Scalapack GCC-15 workaround

• for those auto-building Scalapack, workaround GCC-15 issue due to legacy code style of Scalapack
• rename -DMUMPS_find_SCALAPACK and -DMUMPS_find_static

FindLAPACK oneMKL / AOCL fixes

FindLAPACK had typos fixed that might have made finding oneMKL or AOCL LAPACK fail.

MUMPS 5.8.0 upstream

• MUMPS 5.8.0 upstream default. As always, can optionally choose a different version by setting CMake option -DMUMPS_UPSTREAM_VERSION=5.7.3 or similar
• don't apply host optimization flags as they can break some builds
• add -fno-strict-aliasing for GCC as recommended
• oneAPI Fortrtan C_BOOL flags for consistency
• rename options more specifically MUMPS_matlab MUMPS_scotch MUMPS_metis MUMPS_parmetis
• Fix MUMPS 5.3.x source bug that failed CMake configure

Capable of building MUMPS 5.1.x through MUMPS 5.8.x.

CMake >= 3.20: Scalapack find/build more robust

Changes to MUMPS and Scalapack to work in more situations correctly.

Require CMake >= 3.20 (and test 3.20 in CI) to help packaging robustness across platforms.
