[question] Components hide global definitions in layout method about docs HOT 3 OPEN

Hi @marausch

Thanks for your question.

Your observations are right, once components are defined, the global self.cpp_info.xxxdirs are completely ignored, and the components defaults are used instead. So if you want to change the components ones need to do self.cpp_info.components["mycomp"].includedirs = ["inc"] too.

I have tried to make it that way, because it would be a bit more intuitive, in conan-io/conan#13994. But I finally dropped it, too risky, almost impossible to do it without breaking.

Hi @memsharded,

I was just asking because I probably didn't read the documentation thoroughly (I haven't found where this is explained in the documentation).

Thank you.

Thats fair, moving this ticket to docs, lets try to add some clarification.
