How to Build

On Windows with Visual Studio's CLI

set SDL2_DIR=path_to_your_sdl2_folder
cl /Zi /MD /I.. /I..\.. /I%SDL2_DIR%\include /I..\libs\gl3w main.cpp ..\..\backends\imgui_impl_sdl.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp ..\libs\gl3w\GL\gl3w.c /FeDebug/example_sdl_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x86 SDL2.lib SDL2main.lib opengl32.lib /subsystem:console
#          ^^ include paths                                 ^^ source files                                                                                  ^^ output exe                    ^^ output dir   ^^ libraries
# or for 64-bit:
cl /Zi /MD /I.. /I..\.. /I%SDL2_DIR%\include /I..\libs\gl3w main.cpp ..\..\backends\imgui_impl_sdl.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp ..\libs\gl3w\GL\gl3w.c /FeDebug/example_sdl_opengl3.exe /FoDebug/ /link /libpath:%SDL2_DIR%\lib\x64 SDL2.lib SDL2main.lib opengl32.lib /subsystem:console

On Linux and similar Unixes

c++ `sdl2-config --cflags` -I .. -I ../.. -I ../libs/gl3w main.cpp ../../backends/imgui_impl_sdl.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp ../libs/gl3w/GL/gl3w.c `sdl2-config --libs` -lGL -ldl

On Mac OS X

brew install sdl2
c++ `sdl2-config --cflags` -I .. -I ../.. -I ../libs/gl3w main.cpp ../../backends/imgui_impl_sdl.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp ../libs/gl3w/GL/gl3w.c `sdl2-config --libs` -framework OpenGl -framework CoreFoundation
