GLVND separates -context libraries from OpenGL itself; OpenGL lives in "libOpenGL", and -contexts are defined in "libGLX" or "libEGL". GLVND is currently the only way -to get OpenGL 3+ functionality via EGL in a manner portable across vendors. -Projects may use GLVND explicitly with target ``OpenGL::OpenGL`` and either -``OpenGL::GLX`` or ``OpenGL::EGL``. - -Projects may use the ``OpenGL::GL`` target (or ``OPENGL_LIBRARIES`` variable) -to use legacy GL interfaces. These will use the legacy GL library located -by ``OPENGL_gl_LIBRARY``, if available. If ``OPENGL_gl_LIBRARY`` is empty or -not found and GLVND is available, the ``OpenGL::GL`` target will use GLVND -``OpenGL::OpenGL`` and ``OpenGL::GLX`` (and the ``OPENGL_LIBRARIES`` -variable will use the corresponding libraries). Thus, for non-EGL-based -Linux targets, the ``OpenGL::GL`` target is most portable. - -A ``OpenGL_GL_PREFERENCE`` variable may be set to specify the preferred way -to provide legacy GL interfaces in case multiple choices are available. -The value may be one of: - -``GLVND`` - If the GLVND OpenGL and GLX libraries are available, prefer them. - This forces ``OPENGL_gl_LIBRARY`` to be empty. - - .. versionchanged:: 3.11 - This is the default, unless policy :policy:`CMP0072` is set to ``OLD`` - and no components are requested (since components - correspond to GLVND libraries). - -``LEGACY`` - Prefer to use the legacy libGL library, if available. - -For EGL targets the client must rely on GLVND support on the user's system. -Linking should use the ``OpenGL::OpenGL OpenGL::EGL`` targets. Using GLES* -libraries is theoretically possible in place of ``OpenGL::OpenGL``, but this -module does not currently support that; contributions welcome. - -``OPENGL_egl_LIBRARY`` and ``OPENGL_EGL_INCLUDE_DIRS`` are defined in the case of -GLVND. For non-GLVND Linux and other systems these are left undefined. - -macOS-Specific -^^^^^^^^^^^^^^ - -On macOS this module defaults to using the macOS-native framework -version of OpenGL.
