Only Windows-MSYS2-UCRT64 supported(currently). Try binary. I am not familiar with the Linux environment, so I have only compiled and tested it under the Windows operating system.

Following guide download and install the installer. Then open the MSYS2-UCRT64 shell and install these packages:

pacman -S --needed base-devel mingw-w64-ucrt-x86_64-toolchain
pacman -S git
pacman -S mingw-w64-ucrt-x86_64-cmake
pacman -S mingw-w64-ucrt-x86_64-glfw

After installing the environment, open the MSYS2-UCRT64 shell and execute the following command:

git clone https://github.com/azula1A89/mindmap.git
cd mindmap
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
ninja
