I looked on libb64, as it is not using autoconf/automake
you can not use the default src_* but you need to define them.

As the Makefile is building only static lib and has no install
procedure I modified to build only shared and I used
cygport for the installation.
I also separated the test.

See attached update cygport and patch.
