Windows: oneapi/msvc consistency (#39180)
Currently, OneAPI's setvars scripts effectively disregard any arguments
we're passing to the MSVC vcvars env setup script, and additionally,
completely ignore the requested version of OneAPI, defaulting to whatever
the latest installed on the system is.

This leads to a scenario where we have improperly constructed Windows
native development environments, with potentially multiple versions of
MSVC and OneAPI being loaded or called in the same env. Obviously this is
far from ideal and leads to some fairly inscrutable errors such as
overlapping header files between MSVC and OneAPI and a different version
of OneAPI being called than the env was setup for.

This PR solves this issue by creating a structured invocation of each
relevant script in an order that ensures the correct values are set in
the resultant build env.

The order needs to be:

1. MSVC vcvarsall
2. The compiler specific env.bat script for the relevant version of
   the oneapi compiler we're looking for. The root setvars scripts seems
   to respect this as well, although it is less explicit
3. The root oneapi setvars script, which sets up everything else the
   oneapi env needs and seems to respect previous env invocations.

Spack is a multi-platform package manager that builds and installs multiple versions and configurations of software. It works on Linux, macOS, and many supercomputers. Spack is non-destructive: installing a new version of a package does not break existing installations, so many configurations of the same package can coexist.

Spack offers a simple "spec" syntax that allows users to specify versions and configuration options. Package files are written in pure Python, and specs allow package authors to write a single script for many different builds of the same package. With Spack, you can build your software all the ways you want to.

See the Feature Overview for examples and highlights.

To install spack and your first package, make sure you have Python. Then:

$ git clone -c feature.manyFiles=true https://github.com/spack/spack.git
$ cd spack/bin
$ ./spack install zlib

Documentation

Full documentation is available, or run spack help or spack help --all.

For a cheat sheet on Spack syntax, run spack help --spec.

Tutorial

We maintain a hands-on tutorial. It covers basic to advanced usage, packaging, developer features, and large HPC deployments. You can do all of the exercises on your own laptop using a Docker container.

Feel free to use these materials to teach users at your organization about Spack.

Community

Spack is an open source project. Questions, discussion, and contributions are welcome. Contributions can be anything from new packages to bugfixes, documentation, or even new core features.

Resources:

Contributing

Contributing to Spack is relatively easy. Just send us a pull request. When you send your request, make develop the destination branch on the Spack repository.

Your PR must pass Spack's unit tests and documentation tests, and must be PEP 8 compliant. We enforce these guidelines with our CI process. To run these tests locally, and for helpful tips on git, see our Contribution Guide.

Spack's develop branch has the latest contributions. Pull requests should target develop, and users who want the latest package versions, features, etc. can use develop.

Releases

For multi-user site deployments or other use cases that need very stable software installations, we recommend using Spack's stable releases.

Each Spack release series also has a corresponding branch, e.g. releases/v0.14 has 0.14.x versions of Spack, and releases/v0.13 has 0.13.x versions. We backport important bug fixes to these branches but we do not advance the package versions or make other changes that would change the way Spack concretizes dependencies within a release branch. So, you can base your Spack deployment on a release branch and git pull to get fixes, without the package churn that comes with develop.

The latest release is always available with the releases/latest tag.

See the docs on releases for more details.
