# This program wraps around pkg-config to generate the correct include and
# library paths when cross-compiling using a sysroot.
# The assumption is that the sysroot contains the .pc files in usr/lib/pkgconfig
# and usr/share/pkgconfig (relative to the sysroot) and that they output paths
# relative to some parent path of the sysroot.
# This assumption is valid for a range of sysroots, in particular: a
# LSB-compliant root filesystem mounted at the sysroot, and a board build
# directory of a Chromium OS chroot.

# Some sysroots, like the Chromium OS ones, may generate paths that are not
# relative to the sysroot. For example,
# /path/to/chroot/build/x86-generic/usr/lib/pkgconfig/pkg.pc may have all paths
# relative to /path/to/chroot (i.e. prefix=/build/x86-generic/usr) instead of
# relative to /path/to/chroot/build/x86-generic (i.e prefix=/usr).
# To support this correctly, it's necessary to extract the prefix to strip from
# pkg-config's |prefix| variable.
