Allow CMake to generate query_config.c

Browse source 
This one was trickier for two reasons:

1. It's used from another directory, see
https://gitlab.kitware.com/cmake/community/-/wikis/FAQ#how-can-i-add-a-dependency-to-a-source-file-which-is-generated-in-a-subdirectory

2. The C file being generated after CMake is run means CMake can't
automatically scan for included headers and do its usual magic, so we
need to declare the dependency and more importantly the include path.
