To some extent, this is user error.  My demo.sh script added dummy
top-level projects for each source directory because the projects buried
inside Project-Debug at build are so different from what my developers expect.

If I open mymain.c not from the _demo dummy project, but rather from
Project-Debug at build/[Source Directory]/mymain.c, then right-clicking
on "Open Declaration" does find the line of the .h file that declares
the function.

But this doesn't work in our real world app, so I guess I have to find
a better minimal test case.  I did check the project's "C/C++ Include Paths"
property, and the Include Paths property does list all my source directories,
so that's not it.
I guess I'll try to put together a better minimal test case, and use
the latest cmake from git.
