removing the line that contains qt6_add_ui get's by that problem as widgets are imported by the
Qt6 Setup
find_package(Qt6 REQUIRED COMPONENTS Widgets)
Also SavingThread.cpp has #include "SavingThread.h " Note the space after .h #include "ui_CameraConnectDialog.h" in CameraConnectDialog.h is wrong. Was not able to get to compile even with these fixes.
qt_add_ui doesn't import Widget targets but instructs Qt to compile the ui files into actual C++ objects (like the CameraConnectDialog.ui -> ui_CameraConnectDialog.h) why you can't find it.
I changed it from qt6_add_ui to the versionless command and compiled it with MinGW to fix some compiler warnings and switched to C++17. Adjust the CMakePresets.json accordingly and check if this works for you.
Sorry, it didn't work.

You need to add a configure and build preset for your compiler. I'm not on a Unix system, so the example paths in the file are only working on my Windows system. If you have a standard installation of OpenCV & QT, add the respective paths to your GCC configurations and feel free to do a PR.
Is there no simpler way to compile this program. I've tried several thousands of times now. I was only able to successfully compile this program under Ubuntu 22.04 LTS. Every other attempt in VS fails because of some compiler mismanagement. There has to be a simpler way to do this.
@nincube8 The switch to cmake was effectively exactly that: A switch to the current QT6+ build system recommendation. I tested this on VSCode on Windows 11 without any problems.
But please help me a little solve your issue! What is your current setup, the error (messages) you run into, what have you tried and what's your gut feeling on why it's failing? As I wrote somewhere else: This is my Bachelor project and I can not be bothered to rewrite that shitty code...
I'll post some errors I'm getting. It's probably just because I don't really understand since I'm not formally educated in the issues of code compilation. I load the project by selecting the "Workspace Folder" then selecting the "Live-Video-Magnification" folder.... The option to build the project is greyed out... Visual Studio offers to auto generate the CMake Cache... in the solution explorer with a Debug option Upon clicking that button this happens
-When I'm compiling for the "Local Machine" as a "x64 Release, or any other option available", VS doesn't have a target to build, it's just greyed out. -"Build + Intellisense" Generates an error @ Line 73 in the file "CMakeTestCXXCompiler.cmake" Line 73: "message(FATAL_ERROR "The C++ compiler\n "${CMAKE_CXX_COMPILER}"\n"" "is not able to compile a simple test program.\nIt fails " "with the following output:\n ${_output}\n\n" "CMake will not be able to correctly generate this project.") -Then it goes back to line 1 And outputs this error..... Visual Studio supports CMakePresets.json files versions 2 to 9. Please update your CMakePresets.json file. More info: aka.ms/cmakepresetsversion -If I attempt to change the version # in code @ line 2 from 10 to any other number in "CmakePresets.json", the first error in intellisense disappears, but it still generates the second error about versions 2-9 are supported. "Visual Studio supports CMakePresets.json files versions 2 to 9. Please update your CMakePresets.json file. More info: aka.ms/cmakepresetsversion"
So I attempt to use cmake-gui 3.31.5 to configure the toolchain file for configuring cmakelists.txt -I specify the generator to Ninja and get this error. "CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage Configuring incomplete, errors occurred!"
@nincube8 I advise you using VSCode as is written in the Build section in the README
Install Qt >= 6 Download precompiled OpenCV binaries or compile OpenCV >= 4 yourself In CMakePresets.json Set CMAKE_PREFIX_PATH to the Qt installation directory which should be the same compiler as your OpenCV binaries Set CMAKE_MAKE_PROGRAM to the generator of your choice, Ninja is recommended Set OpenCV_DIR to the directory where the OpenCVConfig.cmake is located Append the path to the OpenCV and Qt binaries to the PATH variable
I only tested this on Windows with VSCode. Make sure to install Qt msvc2022 and Tools, use pre-built OpenCV 4.10 from their website, make sure to install all VSCode Qt Extensions and set User Preferences > CMake: Use VS Developer Environment to "always".
According to https://doc.qt.io/qt-6/qt-add-ui.html qt_add_ui() was added in Qt 6.8, @iplayfast is using Qt 6.6.
I had the same issue on Debian 12 (Qt 6.4.2 even). set(CMAKE_AUTOUIC ON) and commenting the qt_add_ui() line worked for me.
I am using the following Presets. CMakePresets.json
@nincube8 were you successfull in the meantime? I added a .exe to the releases. It is now also possible to build a standalone with OpenCV and Qt being statically compiled via vcpkg. I also updated the readme on how to build with prebuild libraries.
This is updated to be build with vcpkg or prebuild binaries. Please open a new issue if it persists
