Compile-time information about OpenGL extensions.
Each extension is a
struct named hierarchically by prefix, vendor and extension name taken from list at Support state, for example
GL::Extensions::ARB::texture_storage. Note that desktop extensions are available only on desktop build, OpenGL ES 2.0 extensions which are part of ES 3.0 are available only on OpenGL ES 2.0 build, vendor OpenGL ES extensions are available only on OpenGL ES builds and WebGL extensions are available only on WebGL builds.
Each struct has the same public methods as the Extension class (requiredVersion(), coreVersion() and string()), but these structs are better suited for compile-time decisions rather than Extension instances. See Context::
This library is built if
WITH_GL is enabled when building Magnum. To use this library with CMake, you need to request the
GL component of the
Magnum package and link to the
find_package(Magnum REQUIRED GL) # ... target_link_libraries(your-app Magnum::GL)
