Is foo2.txt in ADD_EXECUTABLE() a typo? Could you provide a minimal but
complete example which exposes your issue for detailed investigation?
The DEPENDS clause of custom targets/commands should always be used
with *full* paths, even if the concerned files are generated in the
same CMakeLists.txt, since the behavior w.r.t. relative paths isn't
specified. So, you might retry with DEPENDS ${CMAKE_CURRENT_BINARY_
DIR}/foo.ext. Besides, the GENERATED property doesn't need to be set
on files generated by ADD_CUSTOM_COMMAND(OUTPUT ...) as this is done
automatically.
