generates mandelbrot and julia fractals
requires SDL2
install sdl with your package manager https://wiki.libsdl.org/SDL2/Installation
mkdir build
cd build
cmake ..
cmake --build .
If SDL2 can't be located, then add the root folder containing the lib and cmake files to "MAKE_INSTALL_PREFIX":
cmake -DCMAKE_INSTALL_PREFIX="@PATH@" ..
e.g. PATH="C:/VSLib/SDL2-2.28.4"
OR you update the MAKE_INSTALL_PREFIX list in CMakeLists.txt
