This allows users to use relative paths for mirrors and repos and other things that may be part of a Spack environment. There are two ways to do it.
1. Relative to the file
```yaml
spack:
repos:
- local_dir/my_repository
```
Which will refer to a repository like this in the directory where `spack.yaml` lives:
```
env/
spack.yaml <-- the config file above
local_dir/
my_repository/ <-- this repository
repo.yaml
packages/
```
2. Relative to the environment
```yaml
spack:
repos:
- $env/local_dir/my_repository
```
Both of these would refer to the same directory, but they differ for included files. For example, if you had this layout:
```
env/
spack.yaml
repository/
includes/
repos.yaml
repository/
```
And this `spack.yaml`:
```yaml
spack:
include: includes/repos.yaml
```
Then, these two `repos.yaml` files are functionally different:
```yaml
repos:
- $env/repository # refers to env/repository/ above
repos:
- repository # refers to env/includes/repository/ above
```
The $env variable will not be evaluated if there is no active environment. This generally means that it should not be used outside of an environment's spack.yaml file. However, if other aspects of your workflow guarantee that there is always an active environment, it may be used in other config scopes.
For opt-in packages in Spack, its common that the `cuda` variant
is disabled by default.
This also simplifies downstream usage in multi-variants for
backends in user code.
* Allow the bootstrapping of clingo from sources
Allow python builds with system python as external
for MacOS
* Ensure consistent configuration when bootstrapping clingo
This commit uses context managers to ensure we can
bootstrap clingo using a consistent configuration
regardless of the use case being managed.
* Github actions: test clingo with bootstrapping from sources
* Add command to inspect and clean the bootstrap store
Prevent users to set the install tree root to the bootstrap store
* clingo: documented how to bootstrap from sources

- as outlined in merge-request #21336 some clang compilers
can trigger erroneous floating point exceptions.
OpenFOAM normally traps FPE, but disable this in the etc/controlDict
for specific compilers:
change "trapFpe digit;" -> "trapFpe 0;"
Eliminate previous use of FOAM_SGIFPE env variable in favour of
using the etc/controlDict setting - cleaner and robuster.

This check is performed in cmake_args rather than with a 'conflicts'
statement because matching on !clang (i.e. any compiler that is not
clang) cannot currently be done with our spec syntax.
