[CMake] Fwd: linking libraries at many levels

Tue Aug 25 10:11:59 EDT 2009

My message bounced due to size limitations (!?). I'm resending it without
the appended previous replies.

In case you'd like to see the compilation too, here's the complete output.
The 1A's and 1B's real name is wammoves and inout and the 2C's is wammates.

yarp is an external 3d party libraries framework for robot software, it's
all under the yarp-2.2.2 folder, the rest is my code. So you see something
wrong about yarp? It didn't give any headache when it was all in just one
big file.
