Switch the order of the commands so that when ADD_LIBRARY sees the 
source file it already knows that there is a rule to build it and will 
not complain that it does not exist.

ADD_CUSTOM_COMMAND( OUTPUT ${luawraps_BINARY_DIR}/src/wxLuaWrap.cpp
    COMMAND ${luawraps_BINARY_DIR}/src/wrap.bat
    DEPENDS ${luawraps_BINARY_DIR}/src/luasetup.h
            ${luawraps_SOURCE_DIR}/src/luawraps.i)
ADD_LIBRARY( luawraps
    luawrap.cpp
    ${luawraps_BINARY_DIR}/src/wxLuaWrap.cpp)
