Caesium is an image compression software that helps you store, send and share digital pictures, supporting JPG, PNG and WebP formats.
You can quickly reduce the file size (and resolution, if you want) by preserving the overall quality of the image.

You need to configure CMake first and the command is slightly different for all the platforms: Change the path in variables with the correct directories of the requirements.
cmake -B build_dir -DCMAKE_PREFIX_PATH=/path/to/Qt/version
cmake -B build_dir -DCMAKE_PREFIX_PATH=/path/to/Qt/version/macos -DSPARKLE_INCLUDE_DIR=/Library/Frameworks/Sparkle.framework/Headers -DLIBSSH_INCLUDE_DIR=/libssh/dir/include
Make sure you have all the requirements installed with you own package manager
cmake -B build_dir -DCMAKE_PREFIX_PATH=/path/to/Qt/version/gcc_64
Then you can build with
cmake --build build_dir --config Release --target caesium_image_compressor
