- **[cpprestsdk] fix clang build on new zlib**
- **./vcpkg x-add-version --all**
Defining `dllimport` is *bad* and breaks clang, and since this is in
maintaince mode they aren't going to fix it.
This had the ability to blow up projects before, but newer zlib versions
use `__has_declspec_attribute`, so that makes it impossible to even
_build_ cpprestsdk on systems like these (I'm on Fedora 40).
