Hi,

That question may look stupid for those more experienced than me with Cmake, but will c++20 modules make Cmake packages (using cpack) less relevant if only targeting c++ libs?  
My idea is that you will have everything you need in a module without the need to create a package.

But again, I may generate a lot of nonsense by writing this (and I don’t realize).

Thanks,

No, you still need libraries, config files, and more.
