[CMake] Export target geometric_simu

[jmirabel]

In #69 I removed the export of geometric_simu. First of all, let me remind that the exported target isn't used (and I don't see how it could be used). Now, if you want to reintroduce the export, here is a way of reproducing the issue.

Keeping the old installation path for geometric_simu, i.e. prefix/bin, use roscore in one terminal and rosrun dynamic_graph_bridge geometric_simu in another.

Using the current installation path for geometric_simu, i.e. prefix/lib/dynamic_graph_bridge, and exporting target geometric_simu, try to compile any package that depends on dynamic_graph_bridge.

I do not think this is an issue. If geometric_simu executable is needed by another package this would create a run_depend entry in the file package.xml of the other package and a ADD_PROJECT_DEPENDENCY in the CMakeLists.txt (or in the catkin_depends following the ROS way).
So I am closing the issue. Feel free to repoen it if you think I misunderstood it.

I just need to understand how to do that, even if it's not useful right now :)
