Question

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.

You can mark the .cpp files as “header file only” like this:

# find all filenames in the lib path and gather them in $YOUR_LIB
FILE(GLOB YOUR_LIB path_to_library/*.?pp)

# create a seperate sourcegroup so it doesn't clutter up the rest of your code
SOURCE_GROUP(\\lib FILES ${YOUR_LIB})

# mark them as header-file only
SET_SOURCE_FILES_PROPERTIES(${YOUR_LIB} PROPERTIES HEADER_FILE_ONLY TRUE)

# add both your code and the lib-code to the project
ADD_EXECUTABLE(program ${YOUR_CODE} ${YOUR_LIB})
