That build script consists only of ex-commands, so you can omit the
leading colons and run Vim in batch mode as follows:

vim -esS build.vim

see
:help -e
:help -s-ex
:help -S

If you want your vimrc to be used, you will need to explicitly add a -u
argument for it.

You don't need a GUI, so no need to use gvim. If you don't _have_ a
Console Vim (and are on Windows), well, I don't know if you can avoid
opening the GUI. But you can try replacing vim by gvim in the above command.
