So, it seems to me that the most reasonable way to support more build systems
without duplicating data between them is to enhance pkg-config support. In fact,
.pc files can be as rich as our .pri modules, containing extra data in custom
variables, and build systems can rely on original pkg-config tool or parse .pc files
directly (it's a simple declarative format, if variable substitutions are not used).

AFAIK there no technical reason why providing .pc files for MSVC and macOS
frameworks would be impossible.
