Suggested change

	raise ConanInvalidConfiguration("libfabric is not available on Windows")
	# FIXME: libfabric provides msbuild project files.
	raise ConanInvalidConfiguration(f"{self.ref} Conan recipes is not supported on Windows. Contributions are welcome.")

The project provides msbuild files, but is not something to be done in this PR. Otherwise it will be too much.

Suggested change

	**{ p: ["yes", "no", "dl"] for p in _providers },
	**{ p: [None, "ANY"] for p in _providers },

I would suggest using any in this case, as users may pass the path of the provider, not related to a loadable library (dl:path), it could be static as well.

--enable-bgq[=yes|no|auto|dl|PATH|dl:PATH]
Enable bgq provider [default=auto] (yes: enable bgq
provider; no: disable bgq provider; auto: enable bgq
provider if possible; dl: enable bgq provider and
build as a loadable library; PATH: enable bgq
provider and use bgq installed under PATH; dl:PATH:
enable bgq provider and build as a loadable library
and use bgq installed under PATH)

I also dislike "auto" as it may result in not reproducible scenarios (we had bugs in CCI), but where in the upstream did you find those default values?

I searched in other package managers too and most of them don't manage those options. Only Gentoo and Ubunut I found doing some configuration:

• https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-block/libfabric/libfabric-1.11.2-r2.ebuild#n43
• https://git.launchpad.net/ubuntu/+source/libfabric/tree/debian/rules?h=ubuntu/jammy#n17

I enabled all features that are not blocked by external dependencies. I agree that it should instead match the project defaults. It was nice to see that they passed in CI at least, though.

I did some changes over this PR, including:

• Removed options that not supported in CCI: cxi, opx, psm2, psm3 and xpmem
• Change option values to None, "ANY", as users can pass "path" and "dl:<path" for providers
• Improved msvc configuration error message as the upstream make msbuild files available
• Enabled verbs by default, it did not fail for me locally, using CCI containers
