Description
This triggers a bunch of compile checks you are probably already doing (via CheckIPOSupported), so let's use the same mechanism we use for
pybind11_add_moduleand skip if the global variable is set when importing pybind11.Suggested changelog entry:
* Skip lto checks and target generation when `CMAKE_INTERPROCEDURAL_OPTIMIZATION` is defined.
