[ros-users] How to make a package depend on another package OR on an external package

[Tinne De Laet]

Hi,

Our kdl_1.0 package depends on eigen.
Before we were just specifying a dependency on the eigen package
provided in the geometry stack as:

<depend package="eigen"/>

Alternatively we can also depend on an external eigen package (e.g.
the ubuntu package libeigen2-dev) as:

<rosdep name="eigen"/>

Now I want to adapt the manifest so that either the ROS package OR the
external package are needed as a dependency.
Does the manifest allow this kind of OR statements?
