Some symbols are unresolved in 2.1.1

[alervd]

I'm trying to upgrade from 2.0.11 to 2.1.1.
I've build 2.1.1 using cmake with deprecated-functions enabled.
Compiles fine, but linker can't find these symbols:

I'm using Microsoft Visual C++ 2022.

make sure you're building libtorrent and your client with the same build configuration, in particular TORRENT_ABI_VERSION. When building with b2 this is controlled by deprecated-functions=.

[alervd]

I'm building with the same configuration and I'm using cmake...
Is this TORRENT_ABI_VERSION should be explicitly defined by my app when linking with libtorrent?
