No, that means that CMake does not scan the c++/c files for #include lines
and create depend information.  The custom commands and inter-target
depends are given to the IDE.  For auto generated files, make sure
the files are in the source list for the target that uses them.  If the
two targets do not link to each other (which is rare), you can use
add_dependency to connect two targets.

So, maybe you could provide a small example of the problem you are
having and it should be simple to fix.
