cmake and eclipse: default include paths?

Question

I have a project that builds with CMake system, and I like to import it in Eclipse. However, when I generate eclipse project files with 'cmake -G "Eclipse CDT4 - Unix Makefiles"' there are no default include paths in Eclipse project(such as /usr/include' or the gcc path for standard headers).

How to fix that in most right way?

System: linux gcc 4.3.3 cmake 2.6.4 eclipse 3.5.1

Answer 1

You have to go to the project properties (right button over the project), "C/C++ include paths and symbols" and add them here as "external include paths".

Answer 2

In your CMakeLists.txt try adding the following two lines:

find_path(STDIO_INCLUDE_PATH stdio.h)
include_directories("${STDIO_INCLUDE_PATH}/dummy/../")

The first line looks up the path for stdio.h, which is located in /usr/include on my system. The second adds this folder to the CMake include path. The /dummy/../ part was added to trick CMake into adding the folder (it wouldn't otherwise), and will eventually get stripped off.

This works for me with CMake 2.8.8 and Eclipse 3.7.2.
