        Compatibility with CMake < 3.5 will be removed from a future version of

        Update the VERSION argument <min> value or use a ...<max> suffix to tell
        CMake that the project does not need compatibility with older versions.

I asked ChatGPT, found some hints:

1. Install CMake and Build Tools: Ensure that CMake and the required build tools are installed on your system. You can install them using the package manager for your OS.

On Ubuntu/Debian: sudo apt-get update sudo apt-get install cmake build-essential

2. Verify CMake Installation: Make sure CMake is correctly installed and accessible from your command line:

cmake --version

3. Set CMake Make Program: Sometimes, CMake needs explicit instructions about which build tool to use. You can set the CMAKE_MAKE_PROGRAM variable to point to the make program.

export CMAKE_MAKE_PROGRAM=/usr/bin/make # Adjust the path if necessary

4. Set Compilers: Ensure that the CC and CXX environment variables point to the correct C and C++ compilers.

export CC=/usr/bin/gcc export CXX=/usr/bin/g++

5. bash install.sh again, now everything is good. if you have any questions, please contact shenfei2031@gmail.com
