Ok, found it. Somehow the output of the command <cmd> in
execute_process(COMMAND <cmd> OUTPUT_VARIABLE <var>) is *not* captured
in <var> when running as a sub-project of a super-build. Because of
that, GetPrerequisites thinks the output of dumpbin.exe is empty and
consequently fails to find the dependencies. I could fix it by having
dumpbin.exe write to a file with the /out option instead and then
reading that file back in, but what really needs fixing is CMake...

I'll try to come up with a minimal test-case and then file a bug report.
