version:             0.8.3
synopsis:            Functional interface for OpenGL 4.1+ and OpenGL ES 2.0+
description:         A functional OpenGL [ES] wrapper library.
                     Made complicated OpenGL APIs easy yet keep flexible enough.
                     Resulting binary size is relatively small so that apps
                     launches faster. Works on both desktop and mobile.

flag UseEGL
  description:
    By default, EGL APIs are used to get OpenGL function pointers.
    If Disabled, use native library instead of EGL. e.g. WGL, GLX or dlsym.
  default: True

flag StaticLinkES3
  description:
    By default, OpenGL ES 3.0 APIs are dynamic linked.
    If Enabled, may cause runtime link error on unsupported environment.
    OpenGL ES 2.0 APIs are always statically linked.
  default: False

flag StaticLinkEGL15
  description:
    By default, EGL 1.5 APIs are dynamic linked.
    If Enabled, may cause runtime link error on unsupported environment.
    EGL 1.4 APIs are always statically linked.
  default: False
