Unable to create .pylib file with Mac Sonoma.

[ChurikiTenna]

I want to compile the library into .dylib file in Mac.
However, cmake --build . fails with 'png.h' file not found error.

git clone https://github.com/aetilius/pHash.git
brew install libpng jpeg ffmpeg
mkdir build    
cd build
cmake ../pHash    
cmake --build .

libpng is already installed.

% brew install libpng            
Warning: libpng 1.6.43 is already installed and up-to-date.

but the png.h location was not in the default /usr/local/include, so I added this to CMakeLists.txt

include_directories("/Library/Frameworks/Mono.framework/Versions/6.12.0/include")

Then, I tried
% cmake ../pHash
% cmake --build .
which produced this error:

then I tried to create phash.dylib from pHash.cpp like this.
% g++ -dynamiclib -o phash.dylib pHash.cpp
It fails with this error:
