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

Simply right click on the file > go to Resource Configurations > Reset to Default... Your header files will be found now, provided that you've written the correct include paths in your project settings.
Starting with version 2.6. 0 CMake includes a generator for Eclipse CDT 4.0 or newer. It works together with the Makefile generators (i.e. "Unix Makefiles", "MinGW Makefiles", "MSYS Makefiles", and maybe "NMake Makefiles").
Built-in Settings. CDT will try to detect built-in compiler symbols and include paths running the compiler with special options and parse the output of this special run. Most compilers provide such an option to print built-in include paths and symbols.
In Eclipse, select File > New > C Project. Enter a project name and choose the root of your source tree as the project location. Click Finish, and you have a CMake project in your workspace.
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".

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.
