[CMake] Disabling warnings in Visual Studio Express 2008

[Werner Smekal]

Hi,

normally I just do

add_definitions( /wd4996 )

http://www.cmake.org/cmake/help/ 
cmake2.6docs.html#command:add_definitions

Despite its name you can also add compiler flags. Compile your program  
with

nmake VERBOSE=1

so that you can see if the compiler flags was successfully added.

Regards,
Werner
