I am not having the build folder.
Run truffle compile in your truffle directory. Then the build folder will be created.
Just as a warning, I originally copied the git files as a git clone from enjin but at the time of doing so their files had been updated to pragma solidity 0.5.3 so when I tried to compile these with the other files we have created I truffle did not want to compile with two different versions 0.5.0 & 0.5.3. I simply went back through and changed the cloned files to the 0.5.0 version of solidity. Works fine now.
Thank you, I will correct that.
