Hello,
I believe the usual way to call cmake is to create the build directory,
change to it and call cmake with the path to the source dir, e.g.
mkdir build
cd build
cmake <path-to-opensg-source-tree>
I typically specify the type of build and the install destination as
well, leading to a cmake call like:
cmake -DCMAKE_BUILD_TYPE=Release
-DCMAKE_INSTALL_PREFIX=$HOME/software/opensg2 <path-to-opensg-source-tree>
This will check for optional components (image format libraries, VTK,
Qt, etc.) and configure the build with what is available.
Cheers,
Carsten
