**Bitcoin's configure script by default will ignore the depends output.** In
order for it to pick up libraries, tools, and settings from the depends build,
you must point it at the appropriate `--prefix` directory generated by the
build. In the above example, a prefix dir named x86_64-w64-mingw32 will be
created. To use it for Bitcoin:
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
