CMake prepends 'lib' to the name by default and I see that for the Mingw
build I do remove it. I'm not sure why I didn't do the same for Linux. I
think the right thing to do would be to actually name the 'wx.so' lib with
the Lua and wxWidgets versions and then symlink wx.so to it as most other
libs do.

In order to use Lua's 'require' you need to have the lua exe linked to a
shared lua.so and the lib you want to 'require' also linked to the same
lua.so. If you will 'require' other Lua C libs then these will also need to
be built and linked against the same lua.so library. This is why the lua.so
lib is not rolled into the wx.so lib and the lua exe linked only to wx.so.

In terms of where to put the lua.so lib, you can put it anywhere. Use
LD_LIBRARY_PATH or the program chrpath to change the rpath of the lua exe
to find it.

Hope this helps,
