The present code logic of cmake-js, in order to determine isNodeApi, assumes that package.json and CMakeList.txt are co-located in a folder. If package.json is not found in the same folder, an error is logged in silly mode, which for most consumers is a silent failure.

This PR redresses the issue by recursively searching parent folders until package.json is found and it's path returned, or the system root file folder is reached, upon which false is returned
