No that is not true, Cmake generates them and that is it. The switch is 
really there. (Project Settings/Link tab )

Just imagine how many days i have bin searching in my life for bugs like 
this, and you should feel happy again. ;-)

What in the world or CRT libraries??

In debug mode i see:

/MDd Creates a debug multithreaded DLL, using MSVCRTD.LIB

But this i do not understand already, because i am not generating DLL??
In release mode i see:

/MD Creates a multithreaded DLL, using MSVCRT.LIB
Same story, but at least it says that it needs MSVCRT.LIB, so i assume 
remove switch /nodefaultlib:"MSVCRT.lib"

And looking at wxLua, i see /MDd for debug, and /MD   for all release 
builds.
In debug mode the switch   /nodefaultlib:"MSVCRT.lib" is there if not 
DLL builds and not unicode

For the moment i only set this switch when debug is ON. ( so also when 
building shared, which does not work anyway in VC6)

I am starting to understand this too :-(
