That happens because DYNLOAD is not defined. If you build with DYNLOAD
defined, it links fine. There is one glitch that has to be fixed when
you do that. The build detects windows.h and then doesn't include
dlfcn.h. [See main.h, lines 17--31.] So I edited CMakeLists.txt so as
to trick the build into not defining HAVE_WINDOWS_H. I don't know
enough about cmake to know the right way to handle this.
