Adds port for octomap within vcpkg. In the development branch many
CMake related changes occured since 1.8.1 which are quite
comfortable for vcpkg integration. Due to this fact for the moment
this package is based on commit
cefed0c1d79afafa5aeb05273cf1246b093b771c an should be migrated to the
next stable version shortly after release.
