Libraries footprint is just too big when deployed with Electron

[mgatelabs]

I'm using lwip in my Electron app and when i'm building the final release version there is about 60 megabytes of build files hanging around that are not needed. I've tested by deleting the obj folders and everything still functions. Could you add a way to remove the intermediate build files after it's been built, so the final packaged size isn't massive and only whats required to actually function?
