CMake : Add build directory to include path

I'm looking for the good way to add the build directory (which is different from my source directory, a git repository) to the include path for gcc, in order to have the classic "config.h" file for portability seen during the compilation.

A more modern approach than the selected answer would be to use

set(CMAKE_INCLUDE_CURRENT_DIR ON)

CMAKE_INCLUDE_CURRENT_DIR - Automatically add the current source and build directories to the include path.

There is also ${CMAKE_CURRENT_BINARY_DIR} which resolves the the subdirectory in the build directory that is currently active.

If your sources are in a subdirectory such as src/ and you want to include files that are being generated from src/CMakeLists.txt then using ${CMAKE_CURRENT_BINARY_DIR} might be what you are looking for.

I was looking for

include_directories (${CMAKE_BINARY_DIR})

To add the build directory in case of out-of-source build.
