From c912e9bb8d5be414fda74b2019deb2a6d2d041a0 Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
Date: Sun, 16 Dec 2018 11:52:18 +0100
Subject: [PATCH] Only prefix with the sysroot a subset of variables
The standard logic of pkg-config is to prefix all absolute paths by
the sysroot defined in PKG_CONFIG_SYSROOT_DIR. However, while some
paths (like includedir, libdir, and paths used in -L and -I options)
indeed need to be prefixed by the sysroot, it is not necessarily the
case for paths that are used on the target. If they get prefixed by
the sysroot, the runtime path on the target is incorrect.
Unfortunately, pkg-config doesn't have a sense of which path needs to
be prefixed by the sysroot, and which path should not be prefixed by
the sysroot.
So, let's simply have a whitelist of paths that should be prefixed:
g_ir_scanner, g_ir_compiler, g_ir_generate, includedir, libdir, mapdir,
pkgdatadir and sdkdir. This list of variables was collected over years of
Buildroot development. All other paths are not prefixed by the sysroot.
