Several problems have been reported with the bundle feature.  Please 
submit this as a bug report here:

Use an out-of-source build.  Then there are zero files put in the source 
tree:

cd /Users/RE/src
mkdir CocoaGL-build
cd CocoaGL-build
cmake ../CocoaGL

Just be sure to remove all CMake-generated files from the source tree 
first.  You'll also have to change the executable output path to be 
${CocoaGL_BINARY_DIR}/bin.
