For an example, if I can get e.g. the <insert number here> ZIPs that
comprise our dependencies, unpack them all into
C:/Projects/krita/msvc/install, and once I point VS Code's CMake Tools
to that folder, it will configure and build Krita without further
intervention. (Our build.cmd script is able to set such an environment
up today.)

Same as above, I'm concerned about hidden hardcoded path requirements
that'll only trigger once the modules are unpacked in a personalized
location. Those can be evaded with DLL lookup paths on Windows, but
given that CMake and pkgconfig modules sometimes hardcode them, it can
cause a configuration failure in the first place.
