* CGNS: Add setting of RPATH on Darwin
This should go in the CGNS CMakeLists.txt, but it isn't there yet and won't be in previous versions, so best to handle it here.
If building on darwin/MacOSX, need to set the RPATH so applications can find shared library correctly.
* Restrict MACOSX_RPATH setting
This has now been added to the CGNS distribution, so the setting of `CMAKE_MACOSX_RPATH` should be restricted to current and previous releases and not upcoming releases.
* CGNS: Allow use of git branch versions
Add ability to use git `master` and `develop` branches of the CGNS library. The `seacas` package sometimes needs to use the `master` or `develop` branch due to some new changes to the parallel I/O implementation in CGNS which has not yet been released.
* CGNS: Reorder to put newest version on top
Based on review comments, place newest version (develop) first in list.
* CGNS: Add option for 64-bit integers
Added the `int64` variant which will build the library using 64-bit integers for certain values. This gives the capability to have models with more than 2 billion cells and/or nodes.
Beginning with CGNS-3.1.0, two new typedef variables have been introduced to support 64-bit mode. The `cglong_t` typedef is always a 64-bit integer, and `cgsize_t` will be either a 32-bit or 64-bit integer depending on how the library was built. Many of the C functions in the MLL have been changed to to use `cgsize_t` instead of `int` in the arguments. These functions include any that may exceed the 2Gb limit of an` int`, e.g. zone dimensions, element data, boundary conditions, and connectivity. In Fortran, all integer data is taken to be `integer*4` for 32-bit and `integer*8` for 64-bit builds.
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
* Update CGNS to be able to be used in Trilinos.
* Updating Trilinos to be able to use CGNS.
* Fixing wrong cmake defines in trilinos for enabling cgns and cleaning up cgns package.
* Changing cgns parallel variant to mpi. Removing explicit dependence on parallel-netcdf in trilinos.
+ The recipe for cgns seems to be wrong. CMake complains about variables set but
not used (`HDF5_NEEDS_ZLIB`, `HDF5_NEEDS_MPI` and `HDF5_NEEDS_SZIP`) and fails
to find HDF5.
+ This change set removes these variables from the cmake configure line,
replacing them with `'-DHDF5_DIR=%s' % spec['hdf5'].prefix`
+ cgns also has trouble with parallel make, so I set `parallel = False`.
