Hi @Mike L,
Welcome to Microsoft Q&A!
Please go to Visual Studio Installer > Modify > Individual components tab > ensure that “vcpkg package manager” is installed.
Then, run the vcpkg command from the Developer Command Prompt again.
If it doesn’t work, please try to add the vcpkg.exe directory to system environment variables by going to Settings > System > Advanced system settings > Environment Variables > System variables > Path > Edit.
It is by default located at: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\vcpkg\vcpkg.exe.
After adding the path, please restart your computer and try again.
Sincerely,
Anna
