There is no 'working vcpkg link'. You need to use exact version of vcpkg for your engine.
Right now there are 23596 vcpkg versions and you must know which one is required by your engine to compile.
On new engines there are
vcpkg.json
files with required version for given TFS commit:
A free and open-source MMORPG server emulator written in C++ - otland/forgottenserver
github.com
ex.

If you don't know vcpkg commit for your engine, all you can do is to download some vcpkg version by date with date similar to your engine release (dates are in "Tags" on vcpkg github site) and try to compile using it. If it fails, get another version and try again.

If you don't have fast PC and few hours/days to find vcpkg version that works with your engine, you can just move to Linux. TFS compiles on Linux with system libraries - you don't need vcpkg. Ubuntu 22.04 should be compatible with TFS 1.5.
