How to make rosbuild package depend on catkin package?

Question

In my rosbuild package I have a dependency one of my catkin packages:

<depend package="myCatkinPackage"/>

Calling rosmake myRosbuildPackage generates an error since the catkin package was not found. I can roscd to both catkin and rosbuild packages. I tried overlaying my rosbuild ws on top of my catkin ws:

$ cd ~/path/to/rosbuild_ws
$ rosws init . ~/path/to/catkin_ws/devel
$ source setup.sh

Now it does not find any rosbuild packages (only the catkin_ws is in the ROS_PACKAGE_PATH). What is the correct way of depending on catkin packages from rosbuild?

I figured out a way to get it to work without involving rosws and setupfiles. I just added the following line to bashrc:

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:~/path/to/catkin_ws/devel/lib/pkgconfig

This looks like a hack. The principle of what you were trying is correct: Overlay the catkin_ws from the rosbuild one.

This is basically what setup.sh does (but it does not add it to bashrc of course). On top of that, the setup file also changes ROS_PACKAGE_PATH to point only on catkin_ws (but not rosbuild_ws), which is kind of counterproductive. The best thing with my solution is that it works ;-)

It just seems to me that setup.sh should do everything you need (e.g. correct ROS_PACKAGE_PATH) and if it doesn't the setup is somewhat wrong, which might get you into trouble later.
