Aaargh, that explains it why I couldn't get it running, as I tried
something similar (but simpler).

I tried it and got following problems:

- Setting SET(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/") won't
help cmake finding the CMakeASMInformation.cmake. I located it there
though. So I fooled it by manually copying into CMakeFIles to get it
going anyway.

- I don't undertsand too muchof what is going on in above files, but I
managed to get may nasm files finaly compiled. Unfortunately cmake want
to call an asm linker. I rather want the c(++) linker to be called. What
must I do to get this?

Cheers,

Prakash
