you have two choices:
Integrated into the main OpenSG build:
Add the individual packages to the OSG_EXTRA_EXTERNAL_MODULES, in
cmake e.g. in the cmake gui edit the value for
OSG_EXTRA_EXTERNAL_MODULES and set it for example to:
OSGContribCompute;OSGContribLwoFile;OSGContribBbqTerrain
The module name can be recovered from the cmake file in the
respective dirs, they follow the pattern:
CMakeLists.Lib.<ModuleName>.txt
Once you run cmake (configure part) it will create the corresponding
OSGBUILD_<ModuleName> variables, e.g. OSGBUILD_OSGContribCompute,
these are off by default. After you switch them on and run cmake
configure again corresponding
OSG_<ModuleName>_SOURCE_DIR entries are generated, point them to the
directory that contains the CMakeLists.Lib.<ModuleName>.txt.
After the final cmake run the modules should be build with the main
OpenSG build.
Standalone, e.g. run cmake
cmake -DOSG_USE_OSGSUPPORT_LIBS:BOOL=True
-DOpenSG_DIR:PATH=<opensg install dir>
-DOSG_SUPPORT_ROOT:PATH=<opensg suppor install dir>
-DCUDA_TOOLKIT_ROOT_DIR:PATH=<cuda toolkit root>
<addons source dir>
but this one was broken, I just committed a fix. It should work now, let
me know if it does not.
kind regards
gerrit
