Conan v2 and new toolchain updates

---

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the conan-center hook activated.

The MesonToolchain does not appear to be passing the -stdlib=libc++ option when building with clang. I don't see any other C++ projects using the new MesonToolchain

@planetmarshall There are some projects using MesonToolchain:

Yes, these are all C projects though. They all delete the libcxx setting.

@planetmarshall In that case, it could be a generator limitation. It may worth opening an issue to Conan client asking about it.

This doesn't appear to work with the new PkgConfigDeps generator - not sure if the recipe is missing something or there's an existing issue.

[uilianries]

You touched a known bug: conan-io/conan#11962

Basically you need a workaround to use pkg_search_module with new cmake generators: https://github.com/conan-io/conan-center-index/blob/master/recipes/libcap/all/test_package/conanfile.py

Not beautiful, but should work.

For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
