For this, you need to follow the instructions as given.

FLTK_WRAP_UI(MyProject ${APPLICATION_FLUIDS}) will create a variable called
MyProject_FLTK_UI_SRCS, you need to reference that variable in the call
to ADD_EXECUTABLE.  All generated files are put into the build directory.
I would recommend that you use "out of source" builds for cmake.  It is very
simple, just specify a different path to your source and binary directories.

ADD_EXECUTABLE(foo ${MyProject_FLTK_UI_SRCS})
