Shell is required to pick up opam environment

[ul]

Not sure how to properly fix it, but having

"findlibPackages": [{"dependency": "js_of_ocaml"}]

gives me an error:

ocamlfind: Package `js_of_ocaml' not found
Dependencies scanned and verified, but failed to build

Stack Trace:

If I change https://github.com/jordwalke/CommonML/blob/ccea57fa15f9ecad27ec3e47e139783864430ba0/build.js#L1148 to

return child_process.execSync(findLib, {shell: "fish"}).toString().trim();

it picks up environment fine.

Probably worth to add shell as a config parameter to CommonML entry in package.json?

[jordwalke]

I don't know if it should go in the package.json because that is shared to everyone regardless of their shell. Maybe as a param to node build.js?

I wonder why this is not handled automatically by execSync.

Yes, you are right, making it a param to the build script is a better idea.
