Cmake : Build directory in include path

Question

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.

Answer 1

Are you looking for this -I$(DIR)?

Answer 2

I was looking for

include_directories (${CMAKE_BINARY_DIR})

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