Well done on getting another release out. It's available in the Gentoo's
Haskell overlay already :-)

You bundle all the GLFW source code. Some systems have the C library
already available as a dynamic library. For gentoo for example we would
prefer to use the existing glfw package than statically linking in
another copy. This would be a good application of configurations,
something like:

flag system-glfw
  description: Use the the system GLFW C library.
               Otherwise use the bundled copy.
  default: False

Library
 ...

 if flag(system-glfw)
   extra-libraries: glfw
 else
   ...
