I'm having issues with a package that I want to build for an SDK. The
package I want to build is dbus-c++ for nativesdk. I have used a recipe
converted from use for building the package for target (which works btw),
see below. The problem is that during the build of the package, the linker
looks for libraries in /opt/.../lib/ etc, which is the default location for
installing the SDK. Of course that fails, since the SDK has not yet been
installed when I'm building it!
I'm guessing this is an issue with the recipe, but looking at the automake
files in the library directory (using -c devshell) has not proven
successful as of yet. The package is configured with autotools.

I have tried both with and without the configure_append, it does not seem
to make any difference. The output from bitbake is this (dots in paths are
mine for readability):
<snip>

</snip>
And if I just try it again I'm also getting this:
<snip>

</snip>
It SHOULD link only against libraries built for the SDK, right? But for
some reason it looks for some of them in /opt/ instead of
/home/zarniwoop/.../build-qemu/tmp/sysroots/.../opt/
