Optional: libpng and zlib for loading and saving grayscale images (LoadPNG_ui8matrix() and SavePNG_ui8matrix() functions)

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j4

You may want to specify compiler options as follow when invoking the cmake command:

cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER="g++" -DCMAKE_CXX_FLAGS="-Wall -O3 -fstrict-aliasing -mtune=native -march=native"

Notice that on Apple M1, if you use AppleClang, you should replace -march=native by -mcpu=apple-m1.

To include half precision functions you have to add the FP16 option (-DFP16=ON) on the cmake command. For now it does not work with intel architecture.

The library is located in build/lib/.
