 Basic instructions on how to build using CMake (CMake 2.4.5 or newer is required)
 
-  svn co http://www.openjpeg.org/svn/trunk
-  cd trunk
-  mkdir bin
-  cd bin
-  cmake .. -DBUILD_EXAMPLES:BOOL=ON
+  svn co http://openjpeg.googlecode.com/svn/trunk openjpeg-read-only
+  cd openjpeg-read-only
+  cmake -G "Unix Makefiles"
   make
-  ./bin/j2k_to_image 
+  ./bin/j2k_to_image
+	
+For MacOSX users, if instructions above fail, try to add "-DCMAKE_OSX_ARCHITECTURES:STRING=i386" to the cmake command above.
+	
+To enable testing (and automatic result upload to http://my.cdash.org/index.php?project=OPENJPEG) : 
+
+	svn co http://openjpeg.googlecode.com/svn/trunk openjpeg-read-only
+  cd openjpeg-read-only
+  cmake -G "Unix Makefiles" -DBUILD_TESTING:BOOL=ON -DJPEG2000_CONFORMANCE_DATA_ROOT:PATH=/path/to/your/JPEG2000/test/files
