get baldr building against midgard
allow linking and including valhalla projects that are built but not installed using the --with-valhalla-* directive
move midgard dep up to the top after c++x11
make possible to use as uninstalled but built dep from other projects
make all the includes use -I to resolve. this is the only way to make them work when the project is a dep of another. somehow forgot this one..
Merge pull request #1 from valhalla/kk_cull

make baldr its own package
