If you are ok with having a package.xml in your upstream (there is no harm
in this), that will make releasing with bloom much easier (and then you can
add any other catkin specific things in the release repository as a patch
if you like).

I am currently looking into a method for better handling building plain
cmake packages (pcl, opencv, flann, and octomap), which should make
building it from source with other dependent ROS packages easier.

Sounds like a job for catkin =p.

Maybe one day when catkin is more ubiquitous you could consider using it as
your default buildsystem.
