Hi Robert,

Here's what I'd add to your CMakeLists.txt:

1.
INCLUDE_DIRECTORIES(${WIRS_BUILD_DIR}/path/to/.{cxx|h}) as appropriate. 
Perhaps in a macro that calls ADD_CUSTOM_COMMAND so you don't have to 
update it.

2.
Try specifying the generated sources as
${WIRS_BINARY_DIR}/${wirs_FLTK_UI_SRCS}

I couldn't find a definition of FLTK_WRAP_UI in my CMake install, so I'm 
not 100% on how it works.

3.
You may need to mark the source files as generated, if something else 
isn't doing so already. Here's how:

SET_SOURCE_FILES_PROPERTIES("${WIRS_BINARY_DIR}/${wirs_FTLK_UI_SRCS}" 
PROPERTIES GENERATED TRUE)

I hope that's of some use to you.
