Build instructions reference missing file

[jeffwheeler]

I am trying to follow the instructions in README.md. Under the Build header, it asks me to run:

cmake -B build -S . -DCMAKE_TOOLCHAIN_FILE=../vcpkg/scripts/buildsystems/vcpkg.cmake

but I don't see the file vcpkg.cmake in my repository. (And also the command seems to reference the parent folder above the repository.)

I think adding an instruction to git clone https://github.com/Microsoft/vcpkg.git in the same folder as OpenAllegroParser would be sufficient.

Your are correct. The build instructions are not very clear about vcpkg.

I will leave this for my future self to improve. Feel free to provide a PR.
