[CMake] help with learning add_library

[Gerhard Gappmeier]

Hi again,

I'v forgotten the envar question in the mail before.
If you really want to set additional options from outside CMakeLists.txt you 
can do this:

add_defintions($ENV{CFLAGS})

using $ENV{} you can access any environment variable.
