I have just found this file: "libs/openFrameworks/utils/ofConstants.h"
//-------------------------------
#define OF_VERSION_MAJOR 0
#define OF_VERSION_MINOR 9
#define OF_VERSION_PATCH 0
#define OF_VERSION_PRE_RELEASE "stable"
//-------------------------------
I guess this is our best bet.
I have another proposition now. Using the current CMake files clutters up the workspace. All oF files are listed under the project now. I think we should create an independent CmakeLists.txt for openframeworks and make it compilable as a library, then we should include it in our Application using ExternalProject functions. So openFrameworks will be listed as an external library and our workspace will be neat and tidy.
What do you guys think?
