[CMake] Baffled by CDT4 link_directories

[Dan Furtney]

I have a CMakelists.txt file that works properly for the “Unix Makefiles” type build (Linux) and for VS 2008. When generating a CDT4 project (Linux) from the same file, library paths are not resolved and the project won’t link. The library paths are specified using the link_directories command exclusively.  The cmake files are at the same level as the “Src” directory that contains all source. I am totally stumped as to why this doesn’t work under CDT4.
