Why not just use the llvm-openmp recipe, ignore the wrapping, and append the openmp argument in downstream recipes?

Edit: Adding yet another openmp to conan is not ideal. I recommend recipes add the argument, rather than bloating the ecosystem @jcar87 @planetmarshall @memsharded

Recall that it is also possible to inject compiler flags with tools.build:cxxflags, so adding arbitrary flags can be done from the user side without really modifying libraries.

@memsharded I do recall that, but the proposed openmp/system is mostly concerned with correct handling OpenMP as a part of the dependency graph (that is, correct visibility of the runtime library dependency via the transitive_libs=True attribute and propagating the preprocessor flag via transitive_headers=True for public headers that rely on OpenMP features) rather than a mere optimization flag. Also, I hope you're not seriously suggesting force-enabling OpenMP for all recipes that might support it (#24577 (comment))?

I would explicitly define requirements in packages, rather than wrapping them, which is a workaround. I wouldn't expect force-enabling openmp, rather, it would be an option- for all recipes that might support it.
