This PR adds CMake options that can be used to disable specific features.

  • CINDER_DISABLE_ANTTWEAKBAR can be used for disabling support and compilation of AntTweakBar sources when there is no requirement for a GUI through the specific library.

  • CINDER_DISABLE_AUDIO can be used for disabling audio support. With this option no audio source files will be included in the build process and no audio libraries will be part of the linking process.

  • CINDER_DISABLE_VIDEO same as above but for video support.

The motivation behind this is reduced build times in scenarios where the above features are not required.

time reports a reduced build time by ~28% on macOS through clang and by ~23% on Linux with gcc when all of these options are enabled.

Also, in the case of Linux, disabling audio or/and video features means that the user can skip the installation of the relevant library dependencies ( e.g GStreamer for video ).
