wgl: Allow building libgallium_wgl as a static library.
This is convenient when building zink as opengl32.dll, as it can then be used as a drop-in replacement for Wine builtin opengl32.dll without requiring an extra DLL alongside it.
Alternatively this could use meson both_libraries
, then use
get_shared_lib()
/ get_static_lib()
based on the option but I
couldn't find a good way enable build by default and install by
default only for one of the flavor. If it's not an issue to build
and install both shared and static libraries all the time, we could
use that instead.
