OpenMPI includes cuda_runtime.h, which errors with `#error --
unsupported GNU version! gcc versions later than 9 are not supported!`
By inheriting CudaPackage, the proper conflicts between `cuda` and
`gcc`/`clang` are added.
* mesa, mesa18: Implement the swr variant consistently between mesa and mesa18
* mesa: Bump to 21.3.7
* mesa: Build release by default tie swr to release builds
* mesa, mesa18: re-enable the llvm variant by default
This reverts the change made in #29360
* mpich: add 3.4.3, 4.0, 4.0.1
* mpich: add url_for_version function
For versions 4.0 and up, get tarballs from GitHub. This will help with
CI builds, since the MPICH website denies the urllib user-agent from
downloading release tarballs.
* mpich: disable cuda support
MPICH is failing to build in CI due to a configuration script bug in
detecting CUDA support. Disable CUDA support by default until we add a
proper variant.
Allow declaring possible values for variants with an associated condition. If the variant takes one of those values, the condition is imposed as a further constraint.
The idea of this PR is to implement part of the mechanisms needed for modeling [packages with multiple build-systems]( https://github.com/spack/seps/pull/3). After this PR the build-system directive can be implemented as:
```python
variant(
'build-system',
default='cmake',
values=(
'autotools',
conditional('cmake', when='@X.Y:')
),
description='...',
)
```
Modifications:
- [x] Allow conditional possible values in variants
- [x] Add a unit-test for the feature
- [x] Add documentation
* tests for rewiring pure specs to spliced specs
* relocate text, binaries, and links
* using llnl.util.symlink for windows compat.
Note: This does not include CLI hooks for relocation.

From the tempfile module docs:
The default directory is chosen from a platform-dependent list, but the
user of the application can control the directory location by setting
the TMPDIR, TEMP or TMP environment variables
