pushd %~dp0 will push the directory that contains the file as the working directory and we also pop it at the end to be a good citizen and restore the previous working directory
This script will build both vcpkg and the dependencies needed by Tracy. It puts everything in the vcpkg/vcpkg directory, and changes no other state on the machine. It is perfectly safe to erase the vcpkg/vcpkg directory and re-run the script to build the dependencies again, although that should only be needed once.
To add new vcpkg dependencies, just modify the 'vcpkg install ...' line in the .bat file.
