Building omegalib and omegalib projects

Dependencies

Omegalib libraries and basic can be compiled out of the box without needing any external libraries. Optionally, support for external graphic libraries and toolkits can be added by enabling the specific options inside CMake, and configuring the libraries accordingly.

Python

Omegalib has been tested with Python 2.7

Open Scene Graph

todo

The Visualization Toolkit

todo

Qt

CMake variables

• OMEGA_USE_DISPLAY Enable if you want to write applications that use omegalib to handle graphics.
• OMEGA_BUILD_APPS Enable to build applications, demos and examples included with the omegalib distribution
• OMEGA_BUILD_STATIC (Experimental) When selected, omegalib will be built as a static library.
• OMEGA_USE_PYTHON Enable python support inside omegalib. You need a python library distribution installed
• OMEGA_BUILD_VTK_LIB Enable to build the vtk support library. Vtk applications will be built as well if OMEGA_BUILD_APPS is enabled
• OMEGA_BUILD_OSG_LIB Enable to build the Open Scene Graph support library. Osg applications will be built as well if OMEGA_BUILD_APPS is enabled
• OMEGA_BUILD_QT_LIB Enable to build the Qt support library. Qt applications will be built as well if OMEGA_BUILD_APPS is enabled
