  To help CMAKE find eigen2, OpenCSG, CGAL, Boost, and GLEW, you can use 
  environment variables, just like for the main qmake & openscad.pro. Examples:
 
- OPENSCAD_LIBRARIES=~ cmake .
- CGALDIR=~/CGAL-3.9 BOOSTDIR=~/boost-1.47.0 cmake .
-
+ OPENSCAD_LIBRARIES=$HOME cmake .
+ CGALDIR=$HOME/CGAL-3.9 BOOSTDIR=$HOME/boost-1.47.0 cmake .
+ 
  Valid variables are as follows:
 
  BOOSTDIR, CGALDIR, EIGEN2DIR, GLEWDIR, OPENCSGDIR, OPENSCAD_LIBRARIES
 
+ When running, this might help find your locally built libraries (assuming
+ you installed into $HOME)
+
+ export LD_LIBRARY_PATH=$HOME/lib:$HOME/lib64
+
 2. Location of logs
  
 Logs of test runs are found in tests/build/Testing/Temporary
