Still just use the #include <mylib.h>, and the build will find them?
The problem is wiring isn't defined properly. It's not in the list of programmers. So it may have been done to fix a timing error, but introduced a bug with 100% failure rate. The stk500v2 simply works. When programmers.txt gets updated to define wiring, I'm sure it will fix everything. But until then, this is the only way to get it to work.
