I have the necessary libraries; however, robotgo and the c libraries are expecting the headers to live @ /usr/include rather than /usr/local/include.

What is the best way to get this running on FreeBSD?

I am trying to build a simple example which is based off of the mouse example.

I have X11 libraries and I initially copied some libs from /usr/local/include directly into /usr/include just to satisfy those errors.

I should also note that if I search for the symbols it is complaining don't exist, I can find them:

grep XScreenNumberOfScreen /usr/local/include -r
/usr/local/include/X11/Xlib.h

I tried setting some flags:

export CGO_CFLAGS="-I/usr/local/include"
export CGO_LDFLAGS="-L/usr/local/include"
export CPPFLAGS="$CPPFLAGS -I/usr/local/include"
