From 2a349006b9c1feba0a29ede4838cf8f5fdc0b2e5 Mon Sep 17 00:00:00 2001 From: Hans-Christoph Steiner Date: Tue, 29 Oct 2019 21:13:56 +0100 Subject: force pkg-config to only use --prefix when cross-compiling The current pkg-config setup has no sense of whether it is cross-compiling, so it will detect things on the build system that are not present or are wrong for the host system. This forces the cross-compiling build to only look for pkg-config .pc files in --prefix. A version of this has been the setup for many years with the Android builds.
