CMakeList.txt file tends to have piles of options and seems very complicated. For such situations, you can display configurable options by typing this command.

   1  % cmake -L

You will get very clear result. It's a preferable feature of CMake.

At first, you download files of Collada from here

http://sourceforge.net/projects/collada-dom/

It includes collada-dom, but you must build it before using.

To build the package, you must unpack the zip and move to dom/ directory. And

   1  % make
   2  % make install

That's all.
