 You will need to tell cmake the location of the vcpkg toolchain file. That way, `find_package` will know where to find the installed libraries. If you installed vcpkg in `c:\` as suggested, you invoke cmake like this:

-cmake -G"Visual Studio 17 2022" -D CMAKE_TOOLCHAIN_FILE=c:/vcpkg/scripts/buildsystems/vcpkg ../
+cmake -G"Visual Studio 17 2022" -D CMAKE_TOOLCHAIN_FILE=c:/vcpkg/scripts/buildsystems/vcpkg.cmake ../

 Again, you will need to tell cmake the location of the vcpkg toolchain file. If you installed vcpkg in `c:\` as suggested, you invoke cmake like this:

 If successful, cmake will generate NMake Make files in the build directory. Invoke `nmake` to build the binary.
