Glew has the problem that it has to be selected at build time if GLX or EGL is supported by the library, and this in not encoded in the library name, nor ABI, nor anything. Then it's easy to get into the situation that a binary is built but cannot run because glew supports an API different from the one used by wxWidgets, or the binary fails to link in the end after all objects are compiled. epoxy can support both with the same library avoiding this problem. epoxy is not initialized explicitly, replaced initialization with version check where one was not done already. It seems to be available as vcpkg https://vcpkg.link/ports/libepoxy There are problems related to GL context switching on Windows which does not seem to be used in kicad https://github.com/anholt/libepoxy#known-issues-when-running-on-windows There is also a problem related to multithreaded rendering on Windows https://github.com/anholt/libepoxy/pull/265 It's harder to tell if threading is used for rendering but it does not look like kicad is doing anything complex enough to warrant using multiple rendering threads.
