OpenCascade Example of Face

Simple example of application using OpenCascade. It creates simple face and adds it to the sewing. You can build it at any platform using CMake and make:

mkdir build
cd build
cmake ../
make

# This example shows how to use find_package(OCE) by specifying
# a list of toolkits.
# If a toolkit is missing or if OCE is not found, a fatal error
# is thrown, we do not try to find an Opencascade installation.
