I'm not sure, but I think you can't. 
So actually I think a cmake for DOS should also be built under DOS. And actually this can't be that hard with DJGPP. I "used" it like 10 years ago for a few weeks, when I started to learn C and switched from DOS to Linux. At this time it felt very unDOSish, so probably quite UNIXish.
Maybe it's even still on my old AMD K6 box...
And it really doesn't support long filenames ? Doesn't FreeDOS support them ? I think good old Novell DOS 7 already supported them.
And why does it actually crash in the log you sent ?

Bye
Alex
