[question] how to enforce fPIC transitively

Hi!

I’d like to make sure all of my dependencies have -fPIC enabled, on the os’s where that’s available. I can’t just set the *:fPIC option to true, because not all of the dependencies have an fPIC option.

I know that there are fixes underway for how fPIC is propagated: #8185, but in the interim, I think it would be something like this:

def requirements(self):
    for dep in dependencies:
        if dep has option fPIC:
            set dep fPIC option to True

Obviously that’s mostly pseudocode, but if someone has an example like this, it would be very helpful

that’s awesome, thank you for the rapid response.

I was able to use this, not sure if this is the recommended way, but seems to do the trick:

class USDConan(ConanFile):
    # ...
    default_options = {
        # etc ... ,
        "*:fPIC": True
    }
    # etc ...

Is this correct?
