How do I ignore the build directory in my VCS?

You don't need to, assuming you use git or mercurial! Meson >=0.57.0 will create a .gitignore and .hgignore file for you, inside each build directory. It glob ignores "*", since all generated files should not be checked into git.

meson setup build

will generate build/.gitignore and build/.hgignore.

Can node-gyp configure do same thing?

TIA!
