Those are standalone ready-to-build applications to demonstrate ImGui.
Unfortunately in 2015 it is still a massive pain to create and maintain portable build files.
I choose to provide Visual Studio 10 .sln files and Makefile for Linux/OSX.
Please let me know if they don't work with your setup!
You can probably just import the .cpp files into your own system and figure out the linkage from there.
opengl_example/
OpenGL example, using GLFW + fixed pipeline.

Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
- 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- 2015/03/17 (1.36) - renamed GetItemRectMin()/GetItemRectMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function (will obsolete).
- 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
- 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function (will obsolete).
