- Building with CMake for development is now actually sane - Split deps into projects and extra files - Building against external deps should still work but needs testing - Can now build out of the box without further adjustments as long as SDL(2) is found properly - Build Lua in C++ mode (so it can use exceptions instead of setjmp/longjmp) - Unfortunately we need to enable exceptions for this :( - Remove these defines: * AQUARIA_BUILD_SCENEEDITOR (now always on) * AQUARIA_BUILD_CONSOLE (now always on) * BBGE_BUILD_ACHIEVEMENTS_INTERNAL (now always on unless BBGE_BUILD_STEAMWORKS is defined) * BBGE_BUILD_OPENGL_DYNAMIC (now always on, define BBGE_BUILD_OPENGL_STATIC if needed) * BBGE_BUILD_FMOD_OPENAL_BRIDGE (now always on) - BBGE_BUILD_STEAMWORKS is not actually implemented (any volunteers?) - Prepare later removal of SDL & the old vc90 project from the repo. See #74 for extra notes.
