Detect if jq already exists on the system

[LaurentGoderre]

In my alpine linux container, it is easier to install from package manager that installing all the build tools. It would be nice if there was a way to detect an installed version before building.

Hey @LaurentGoderre

We don't really want to depend on a global installation of jq. But I can see the need.

We could consider add an env var that forces to not download the binary, would that work for you?

[LaurentGoderre]

Absolutely!!

In the meantime, in my Dockerfile, I do a symlink to make it work but it isn't ideal for maintenance.

Hey @LaurentGoderre

Pretty late, but I needed and I implement the NODE_JQ_SKIP_INSTALL_BINARY env variable. It's un-documented right now, but if you set NODE_JQ_SKIP_INSTALL_BINARY=true it will skip the instalation!
