The paths for src2.c and src.c look fine. However, the CMAKE_COMMAND shows:
C:/Program Files/CMake 2.4/bin/cmake.exe
i.e. *without* any quotes. I fear that the spaces in this filename are the
culprit.
For whatever it is worth, did I mention that this is Win98SE? Maybe should
try after quoting the filename..

Yes, I did replace this, and the second call a few lines later. The
configuration DID go thru without any errors, confirming that the file copy
is not happening.
Since the paths are correct, it has to be the spaces in the filename. How
exactly to quote the entire filename?

The build, however is still not successful - It failed while:

Generating cmsysProcessFwd9xEnc.c
Bad command or file name

And the file 'cmsysProcessFwd9xEnc.c' is then not found as expected. Maybe
this also depends on -E copy somewhere else...?
Btw, with the same sources, the linux build went smoothly - the color output
looks great!
