[CMake] Problem with shared libraries

[Marco Spatz]

Hi,

I found the reason for this behavior, and want to make sure, that what I 
am doing is legal before submitting this to the bug tracker:

The reason is that we are changing the LIBRARY_OUTPUT_PATH several times 
in the project, because we want to put each plugin lib in its own directory.

For example:

set LIBRARY_OUTPUT_PATH to project/foo

build shared lib foo (now located in project/foo)

change LIBRARY_OUTPUT_PATH to project/bar

build shared lib bar


CMake 2.2 seems to store foo like ($LIBRARY_OUTPUT_PATH/libfoo.so)

If bar needs to be linked to libfoo.so, the LIBRARY_OUTPUT_PATH has 
changed, and the linker thinks libfoo.so must be in /project/bar/libfoo.so

Now again, is it ok to change the LIBRARY_OUTPUT_PATH during the project?

Ciao,
Marco
