[wjwwood]

Ah, we should probably switch the shim package's build type to cmake, which would solve this.

We do naively assume that all catkin packages will create a devel space.

[tfoote]

The shim packages are pure cmake and are flagged as such.

[dirk-thomas]

The reason is that the package does not actually install any file.
