Hi,

does anyone know how to build on top of catkin stacks that are checked 
out and built from source? Say you have a catkin stack A (containing 
only messages), you build it in the "build" subdirectory and you want to 
compile against it with a stack B? I had hoped to be able to do that by 
just sourcing the autogenerated setup.bash in "build" but it does not 
work (B still finds the system-installed version of A). Essentially, 
this is the standard scenario of overlaying one package with a 
development version, as I want to start porting release code to groovy. 
Installing A globally on the system is a workaround, but this should not 
be necessary as it potentially breaks other code which will start 
linking to wrong versions. Releasing the package A and then waiting for 
the build server to build A, installing it and then working on B is also 
possible but very time-consuming especially if both A and B need to be 
worked on.


Cheers,
