Sounds like you may have the problem with CMake discussed here.

Not sure how to handle that, maybe I should simply cache IS_XX_BIT so
it stays the same between CMake runs.

This line?
const wxIcon* returns = (const wxIcon*)&self->GetIcon(size);
I'm not sure how to convince GCC that this is a not a temporary
variable since it isn't.
Could you try this:
const wxIcon* returns = reinterpret_cast<const wxIcon*>(&self->GetIcon(size));

That's fine, wxWidgets declares a lot of functions deprecated, but
wxLua supports multiple versions. It's unfortunately something we have
to live with, unless I ignore them all with -Wno-deprecated to silence
them, which I probably will.

-fPIC is definitely used for wxLua in 64-bit for everything, is it for
wxWidgets when building staticly? You can probably check by calling
wx-config --cxxflags
This is what's going on. You build wxWidgets statically, and I bet
they don't use -fPIC when building it. wxLua tries to create a shared
libwx.so and links to the static wx libs and you get the -fPIC errors.
Maybe rebuild wxWidgets with
make CXXFLAGS=-fPIC CFLAGS=-fPIC (or do this through configure)

Yes, it is the Lua module that from Lua you call require("wx") to
load, but I have not finished testing it.

Yes, this is intentional. The library libwx.so must always be shared
so it can be dynamically loaded from Lua.

Can you compile the wxWidgets media control sample without error?
