creating windows, contexts and surfaces, reading input, handling events, etc.
GLFW natively supports Windows, macOS and Linux and other Unix-like systems.
Experimental implementations for the Wayland protocol and the Mir display server
are available but not yet officially supported.
Experimental implementations for the Wayland protocol, the Mir display server

The (experimental) Wayland backend also depends on the `extra-cmake-modules`
package, which is used to generated Wayland protocol headers.
The (experimental) EGLDevice backend also depends on the `libdrm-dev`
development package.
The examples and test programs depend on a number of tiny libraries. These are
located in the `deps/` directory.

- @b _GLFW_WAYLAND to use the Wayland API (experimental and incomplete)
- @b _GLFW_MIR to use the Mir API (experimental and incomplete)
- @b _GLFW_OSMESA to use the OSMesa API (headless and non-interactive)
- @b _GLFW_EGLDEVICE to use the EGLDevice API (experimental and incomplete)
If you are building GLFW as a shared library / dynamic library / DLL then you
must also define @b _GLFW_BUILD_DLL. Otherwise, you must not define it.
