+A standard "ccmake ." while in the root of the OSG source will expose
+two CMake variables: COLLADA_INCLUDE_DIR and COLLADA_LIBRARY. Using
+these two variables correctly can be a bit tricky (especially as
+the "right" and "wrong" ways to use Collada are hard to define), but
+I will briefly explain them below.
 
-set the env vars:
+  COLLADA_INCLUDE_DIR: This variable wants the path where it can
+  find the COLLADA headers. On most systems this will be something
+  like /usr/include or /usr/include/collada.
 
-  COLLADA_INSTALLED = yes
-  COLLADA_DAE_HOME = root directory of COLLADA DOM
-   
-  And if you've compiled the debug version of the COLLADA DOM then define:
-  
-  COLLADA_DEBUG_LIBS = yes
-  
-  Note, Collada svn trunk currently defaults to debug build.
-
-The above env vars can also be setup in your own custom Make/depdendencies file (copy this and point
-to the locally modified copy using the env var OSG_DEPENDCIES so the the OSG's build system can find
-it.
-
-//EOF
+  COLLADA_LIBRARY: This variable is asking for the FULL PATH to the
+  file libcollada_dom.a. As long as it can find this file, the
+  OSG Collada ReaderWriter should build just fine.
