    @SGaist Switching between Linux and Win 10 has its hazards. Made the change and got deep into it all the way to:
    CMake Generate step failed. Build files cannot be regenerated correctly.
    qt3d/6.0.1@qt/final:

    What did I screw up this time?

    @ofmrew I got a number of CMake Errors before the line: CMake Generate step failed. Build files cannot be regenerated correctly. I did not include them because there is a limit on the size of a post, been down that road already today. An example is:

    CMake Error at /home/bob/Qt/6.0.1/gcc_64/lib/cmake/Qt6/QtModuleHelpers.cmake:48 (add_library):
    Target "3DExtras" links to target "XKB::XKB" but the target was not found.
    Perhaps a find_package() call is missing for an IMPORTED target, or an
    ALIAS target is missing?
    Call Stack (most recent call first):
    src/extras/CMakeLists.txt:7 (qt_internal_add_module)

    Any suggestions?

        @SGaist said in 3D Install Qt6:

        libxkbcommon

        What is that and were do I find it?

          It's one dependency of the xcb plugin and your distribution package manager should provide it.

                    You are missing the zlib development package.

                      Looks like ZLIB is missing, what is that?

                        @ofmrew I should have waited, I found zlib1g-dev, is that what I need to install?

                                Looks like Vulkan is not as optional as stated in your logs above.

                                From memory, you need that SDK.

                                  @SGaist Thanks for all your help so far, but exactly what do I need because I have looked and I have yet to find an installer for the Vulkan SDK and QVulkanInstance. I am at a loss. You should know because Qt is part of the Khronos group. Please help, we are so close to having 3D installed.

                                  One other question: can I have both -g=cmake and -g qmake and it I have the latter do I need a -g qmake_paths?

                                    The page I linked provides a link to the SDK download page.

                                    You should know because Qt is part of the Khronos group..

                                    I think there's a mistake here. I do not work for the Qt Company.

                                      @SGaist Sorry about that, bad assumption on my part. It makes the help even more outstanding. Can you answer the question: can I have both -g=cmake and -g qmake and it I have the latter do I need a -g qmake_paths?

                                      Also, do you know of a good reference on installing Valkan, I downloaded the sdk from the URL you provided, but I am stuck on how to proceed. Thanks.

                                        Which distribution are you using ? For Ubuntu based there are easy to follow instructions.

                                          Ubuntu

                                          I got these and executed them:

                                          Ubuntu
                                          AMD It's best to enable a PPA for the latest Mesa drivers. There is a PPA that packages and releases the latest changes straight from Mesa's Git. Add the PPA to your system and update. Then, upgrade your system. It will automatically upgrade your existing Mesa packages.

                                          $ sudo add-apt-repository ppa:oibaf/graphics-drivers
                                          $ sudo apt update
                                          $ sudo apt upgrade
                                          When it's done, install the Vulkan packages.

                                          apt install libvulkan1 mesa-vulkan-drivers vulkan-utils

                                          NVIDIA Ubuntu also has a great repository for the NVIDIA proprietary drivers. Add it to your system, and update Apt.

                                          $ sudo add-apt-repository ppa:graphics-drivers/ppa
                                          $ sudo apt upgrade
                                          Now, install your drivers and Vulkan.
                                          $ sudo apt install nvidia-graphics-drivers-396 nvidia-settings vulkan vulkan-utils

                                          But the conan install failed:
