qt-minimalistic-builds

This is attempt to build Qt 5/6 libraries in minimalistic mode. Output binaries have fewer dependencies, are lighter and thus smaller.

All original licenses of all used components (Qt, qtbinpatcher, MinGW-w64, OpenSSL, MSVC) are respected with the additional exception that compiling, linking, and/or using OpenSSL is allowed. Unmodified source code of Qt is used and the license of produced Qt binaries is the same as license used in original OSS Qt libraries. The build phase of these prebuilt binaries is reproducible, see repository files for build scripts.

How this differs from official Qt Windows binaries?

Well, there are some differences:

• all new dynamic builds include slimmed version of QtWebEngine !!!,
• these binaries are compiled with MinGW-w64 or MSVC2019 toolchain with latest updates and are x64,
• some features and modules are disabled, which makes dependency tree smaller (details are specified in description of each release),
• Qt 5.15+ is automatically relocatable but qtbinpatcher.exe is bundled too,
• debug/release builds are available,
• latest manually compiled OpenSSL libraries are used,
• allmost all 3rd-party libs used by Qt are compiled directly into libraries,
• link-time optimizations (/LTCG and /GL) are enabled in MSVC2019 static builds.

How to use

1. Install Visual Studio 2019 or just Build Tools.
2. Download prebuilt Qt binaries and unpack them to folder of your choice, for example C:\Qt\XX.
3. Setup your Qt Creator to use new libraries.
