The Linux version doesn't appear to have the same problem.

I've been trying to build the Windows version this morning. I have it building
except for:

Debuglib.obj : error LNK2001: unresolved external symbol _htsMemoryFastXfr
Debuglib.obj : error LNK2001: unresolved external symbol _htsCallbackErr
Debuglib.obj : error LNK2001: unresolved external symbol _abortLog__
Debuglib.obj : error LNK2019: unresolved external symbol _hts_lowcase
referenced in function _optinclude_file
Debuglib.obj : error LNK2019: unresolved external symbol _linput referenced in
function _optinclude_file
.\Debuglib\libhttrack.dll : fatal error LNK1120: 5 unresolved externals

I'm haven't figured out why the linker is having a problem. Each of the
symbols are defined in various .c source files.
