For c++, your swig file needs to have a swigcxx extension for the go tool to run swig properly.

Then I need to call 'go tool cgo mylib.go'. This creates an _obj directory with a bunch of files. After that I tried calling 'go build'. This errors out when my c++ code refers to some 3d party libs. How can I tell 'go build' additional flags for compiling and linking like -I and -L flags?
