This is a fork of AntTweakBar 1.16 that has been butchered for my own use.

Changes from upstream:

• Removed all rendering backends except OpenGL core
• Removed all event backends except SDL 1.3
• Upgraded SDL 1.3 backend to SDL 2
• Replaced remaining platform-specific code with SDL 2 calls
• Added minimal CMake build file, static lib only
• Removed OpenGL function loader code, added hooks to inject own loader

AntTweakBar is very hacky code (-fno-strict-aliasing should hint at that), so I suggest you don't use this. But if you are, like me right now, in a hurry for a quick&easy UI, here is how:

First, this project is not meant to compile on its own. Instead, include it as a subdirectory in another CMake project. This is mostly because it doesn't ship the (non-standard) FindSDL2.cmake module, but also because you need to define some variables.

# Set this to whatever your OpenGL loader include file is.
# On Linux you could probably get away with GL/gl.h
# This must be defined before everything else.
# You could also pass this on the CMake command-line as -DATB_OPENGL_HEADER=...
set(ATB_OPENGL_HEADER GLXW/glxw.h)

# Now include the subdirectory, easy enough!
# This will provide you with an AntTweakBar target to link against!
add_subdirectory(libs/AntTweakBar-sdl2 EXCLUDE_FROM_ALL)

# Finally, hook AntTweakBar up to your program:
include_directories(SYSTEM libs/AntTweakBar-sdl2/include)
add_definitions(-DTW_STATIC)
target_link_libraries(yourexe AntTweakBar)

AntTweakBar is a small and easy-to-use C/C++ library that allows programmers to quickly add a light and intuitive GUI into OpenGL and DirectX based graphic programs to interactively tweak parameters.

This package includes the development version of the AntTweakBar library for Windows, GNU/Linux and OSX, and some program examples (sources + binaries).
