Once you have generated the appropriate DLLs for OpenCASCADE (there are many of them), you will need to rebuild FreeCAD. Open CMake and set up the source and build directories of a FreeCAD build as directed above. It is generally a good idea to use a new build directory for this alternate version of OpenCASCADE so that it is easy to switch back to your old version of FreeCAD if something goes wrong, and to set up an install directory so you can ensure the correct libraries are in place. In addition to the CMake variables discussed above, set the OpenCASCADE_DIR variable to the location of the cmake folder containing your OpenCASCADE build information. For example: CMAKE_INSTALL_PREFIX   C:/Users/JaneDoe/Work/FreeCAD_occt751-install/ OpenCASCADE_DIR        C:/Users/JaneDoe/Work/opencascade-7.5.1-install/cmake/
