Problem with a package and its dependencies in same workspace

[asmodehn]

When having two dependent packages in the same workspace (happened to me for pyros_common et pyros_interfaces_ros), it seems that one dependency (from pip) can override the local one from source...

Need more investigation...

While checking this we also need to check differences between the pip dependencies and the ROS dependencies...

Currently it looks like python deps override ROS deps... This is :

• good for doing developpement on a package and it s dependency at the same time
• bad for testing that the ROSpackage (and it s dependencies) work fine, since python version will override in dev...
