First of all I warn you: doing such actions leads to unsafe and unstable server's work.
1. Set TRUSWORTHY ON upon desired database
2. Choose WITH PERMISSION_SET = UNSAFE or EXTERNAL_ACCESS
3. Create CLR storing procedure which executes external binaries or uses libs
4. Create CLR trigger which executes CLR stored procedure created

It is not safe at all, so consider not to use this, try to use CLR procedures without executing any external code.
