Build

macOS

  1. Build Qt>=6.2.0
  2. Build OpenSSL and CURL using scripts/build_openssl_curl.sh
  3. Build Chollian Wallpaper using CMake.
  4. Refer github workflow for more details (CMake parameters, etc).

Building Qt can be replaced with installing it using homebrew, and CURL is embedded in macOS natively. Reason for building them is to offer universal binary for both Intel/Apple Silicon. See 2021.10 how we've done it before with homebrew.

Windows

  1. Install Qt6 and CMake

  2. Download pre-built curl. link

  3. Set environment variables.

mkdir build
cd build
cmake -DCURL_LIBRARY=path/to/libcurl.dll.a -DCURL_INCLUDE_DIR=path/to/include ..
MSBuild.exe PACKAGE.vcxproj -p:Configuration=Release
