export COINDIR="/usr/local"
export INCLUDE="/usr/local/include:/usr/local/Trolltech/Qt-4.7/qt/include"

Type configure command for release build:

./configure --enable-debug=no --enable-symbols=no --with-coin=/usr/local --with-qt=/usr/local/Trolltech/Qt-4.7/qt

This will start the configuration process. This process should finish succesfully with the following message:

SoQt configuration settings:
  Open Inventor brand:  Coin
