And that file is included in another file, right ?
I remember the problem, but since nobody complained again I considered it 
The simple and right solution would be to rename the generated included files 
from *.cpp to *.inl and simply add them to the list of source files.
Then everything will just work.

All other options are more or less hacks.
Here we go:

Next option: generated a helper target which depends on the cpp files:

add_custom_target(generator_helper DEPENDS 
${CMAKE_CURRENT_BINARY_DIR}/JSHTMLInputElementBaseTable.cpp ... )
(I didn't look up the exact syntax) and then do
add_dependencies(unity generator_helper)

Then the helper target will be built before the rest and so the files should 
be generated.

Next option: add the generated .cpp files to the list of source files but add 
some weird stuff with #ifdefs so that they are empty for the compiler when it 
tries to compile them separately, but work as expected if they are included.
