Today I figured out what happens really with mingw and cmake
generated makefiles.

It is not the ; - it is the wrong argument for the cd-command
from command.com

@cd c:/src/MyApp

has two incompatibilities, first the drive is not supported,
second the / is not supported.

To troubleshoot this, I tried to postprocess the Makefiles with
a script, but trouble shoots back, because cmake itself is called 
somewhere in the dependency rules :-(

Second approach was to run sh from mingw, but the generated
Makefiles use c:/src but mingw-sh uses /c/src, so it is that
incompatible like with cygwin.


I don't know what exactly setup you have, but for FWIW the MSYS environment comes with a shell that will work well with the "c:/src" syntax.
