[CMake] Passing variable to program

[Adolfo Rodríguez]

If VERSION is a preprocessor definition, you can use the
set_property<http://cmake.org/cmake/help/cmake2.6docs.html#command:set_property>command.
For example, if you want VERSION to be defined only in your main.cc
source, do

set_property(SOURCE main.cc PROPERTY COMPILE_DEFINITIONS VERSION=1.0)

or

set_source_files_properties(main.cc PROPERTY COMPILE_DEFINITIONS VERSION=1.0)

you can also set properties on a per-target or per-directory basis.
