It may be the version of Tcl you are using is before the changes from [TIP 477](https://core.tcl-lang.org/tips/doc/trunk/tip/477.md) were integrated.

For the problem in your post I looked at the a few of the Tcl modules and added the following line to win/makefile.vc:

```
PRJLIBNAME	= $(PROJECT)$(VERSION)$(SUFX).$(EXT)
PRJLIB		= $(OUT_DIR)\$(PRJLIBNAME)
```

You may not need both, but this seemed to be the pattern from other packages. After that I was able to compile the module using Tcl8.6.12. Initially tried 8.6.7 until I read TIP 477. Hopefully this resolves your issue and assist others who have been working on the windows compile.
