I am using CMake to build a project with external libraries by using "Eclipse CDT4 - Unix Makefiles".

Importing in Eclipse leads to a working project, but only all header files and my implemented source files are recognized correctly by the index of Eclipse.
I would also like to navigate through the source files for one external library by using "ctrl+click". I don't know how to add the \*.cpp files of that external library in my CMakeList.txt to get them recognized by the indexer without building the library.
