Hello everyone
When I use cmake-gui to build 3dSlicer,I run into this problem.
CMAKE_DEFAULT_BUILD_TYPE must not be used with CMake >=3.17 (see https://github.com/Slicer/Slicer/pull/4799 for details).
Please use latest stable or master version of Slicer source code and follow the current build instructions: https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/windows.html
