Dummy module to indicate the presence of patchelf.
Used by python3-meson-python.

The CMakeLists.txt file is a crippled copy from this patchelf
python module's sources, removing almost everything, and
adding a dummy install target, so do_install() doesn't fail.

I’m not sure I’d call this a dummy package.

+DEPENDS = "python3-scikit-build-native"

If you’re not building native code with cmake then you don’t need this, just switch skbuild to setuptools.

Use subdir=${S} to put the CMakeLists.txt in the right place instead of doing this.

However, this recipe doesn’t build patchelf and doesn’t have any python code. So what’s the point of it?

If there are packages which depend on this, either patch out that dependency (as we can just DEPEND on patchelf-native) or write the few lines of pyproject.toml to ship an empty package directly.
