In my case, the dependencies of the f.c will be all the dependencies of main.
i.e. if any source file contributing to the exe changes we must first
regenerate f.c.
Now our executable depends on many source files. I assume you are saying that I
need to add the same list of dependencies to the ADD_CUSTOM_COMMAND. Can I
specify a list of files further up in CMakeLists.txt so that I only need to
enumerate the list once?
Regards
David
