    ### Additional Support
    @keaneflynn has created a [repository](https://github.com/keaneflynn/RazerBlade14_OpenCVBuild) that contains a bash script with all the steps to build and install the libraries and a python script to test it over a mp4 video, already attached. Main peculiarity of his installation is the explicitly definition of the gcc and g++ versions. Other folks have also reported incompatibility problems with g++, as @keaneflynn, so I've found interesting to include his repo as an additional support.
    ### EXAMPLE TO TEST OPENCV 4.5.2 with GPU in C++
    Verify the installation by compiling and executing the following example:

    ### List of documented problems
    If you have problems with unsupported architectures of your graphic card with the minimum requirements from Opencv, you will get the following error:
    ```
    CUDA backend for DNN module requires CC 5.3 or higher. Please remove unsupported architectures from CUDA_ARCH_BIN option.
    ```
    It means that the DNN module needs that your graphic card supports the 5.3 Compute Capability (CC) version; in this [link](https://developer.nvidia.com/cuda-gpus) you can fint the CC of your card. Some opencv versions have fixed the minimum version to 3.0 but there is a clear move to filter above 5.3 since the half-precision precision operations are available from 5.3 version. To fix this problem you can modify the *CMakeList.txt* file located in *opencv > modules > dnn > CMakeList.txt* and set the minimum version to the one you have, but bear in mind that the correct functioning of this module will be compromised. However, if you only want GPU for the rest of modules, it could work.
    You can also select the target `CUDA_ARCH_BIN` option in the command to generate the makefile for your current target or modify the list of supported architectures:
    $ grep -r 'CUDA_ARCH_BIN' . //That prompts ./CMakeCache.txt
    The restriction is to have a higher version than 5.3, so you can modify the file by removing all the inferior arch to 5.3

    If you have problems with unsupported architectures we must explecitly define the `CUDA_ARCH_BIN` option in the command to generate the makefile or modify the list of supported architectures. I opted for the second option inspired by the error message:
    ```
    CUDA backend for DNN module requires CC 5.3 or higher. Please remove unsupported architectures from CUDA_ARCH_BIN option.
    ```
    The restriction is to have a higher version than 5.3, so we find the file with the configuration:
    $ grep -r 'CUDA_ARCH_BIN' . //That prompts ./CMakeCache.txt
    So, we modify the file by removing all the inferior arch to 5.3
    ```
    CUDA_ARCH_BIN:STRING=6.0 6.1 7.0 7.5
    ```
    Now, the makefile was created succesfully. Before the compilation you must check that CUDA has been enabled in the configuration summary printed on the screen.
