pybind11 cmakedeps

[lasote]

Specify library name and version: pybind11/all

I'm submitting some changes in the properties and including a new test_package_cmakedeps to make sure the package is correctly consumed with CMakeDeps.

• 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.

Use the same project files (CMakeLists.txt) from test_package, even if you need some if to skip the conanbuildinfo.cmake. It is important to check that both generators use the same find_package call, same target names,...

[lasote]

I don't think that is a good practice:

1. Tricking the layout to include a ../test_package/CMakeLists.txt is very dirty and not something you will do except for this situation.
2. Introducing an IF in the original CMakelists.txt to skip the conanbuildinfo.cmake would be very very weird, so you edit that file and you are supposed to know that is shared between several test_packages.
3. When Conan 2.0 is introduced here, we want to remove/rename the test_package folder and it will require extra effort.
4. I get that using the same target name is important, and that can be checked in the review of the PR.

Overall I think that code reuse, far from helping, will cause more trouble and dirty code.

Thank God it is more or less easy with the layout, just:

    def layout(self):
        cmake_layout(self)
        self.folders.source = os.path.join("..", "test_package")

I find it important, but let's wait for other reviewers, they are the ones that will maintain this recipe and possible inconsistencies between the two files.

I'm pretty sure this is related to #9343 (comment). Is there any news on this PR @jgsogo? 🙂

^{Note: To save resources, CI tries to finish as soon as an error is found. 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.}

I just pulled this locally, and the fix to the CI is simple, in test_cmakedeps/conanfile.py, the line

from conan.tools.cross_building import cross_building

should be updated to

from conan.tools.build.cross_building import cross_building
