[question] Override env var for only one requirement
What is your question?
I have a requirement that misuses a specific env var (CROSS_COMPILE). For this specific package I need to keep that variable empty. On the other hand, it needs to be set for the rest of the dependency chain. This package is down in a long chain of requirements and I do not feel like overriding all recipes of my own just to modify this problem or patch the package, but would like to use the one from conan.io
Is there a way to set an env var to a specific depedant pacakge only, or in some other way modify it?
Have you read the CONTRIBUTING guide?

Hi @rollebolle
Thanks for your question
Is there a way to set an env var to a specific depedant pacakge only, or in some other way modify it?
yes, the [buildenv] section in the profile also admits per-package patterns:
[buildenv]
mypkg/*:SOME_VAR=SOME_VALUE
Defines the env-var only for packages mypkg/*, but not for others.
