[Cmake] Object Suffixes

[Andy Cedilnik]

Hi Zennard,

Simple as this:

Let say you have the following complex project:

PROJECT(WORLD)
ADD_EXECUTABLE(HelloWorld HelloWorld.c)

Ok, so you want to build it on several platforms using the same source
tree.

Let say your path to source is:

/home/z/world

Create directory:

/home/z/world-linux
/home/z/world-sun
...

Then go to each one of them and run

ccmake /home/z/world

And specify specific options for that platform. This will create
makefiles specific for that platform.
