Some notes on how to build KDE Frameworks packages from source on Windows using Visual Studio tools.
To do so, you need to first have a version of Qt compiled by MSVC installed. Some system environment variables to be set, using Qt 5.15.2 as an example:
PATH
needs to addC:\Qt\5.15.2\msvc2019_64\bin
Qt_DIR
needs to be set toC:\Qt\5.15.2\msvc2019_64
Example instructions for building CMake-based projects (all KDE projects), the command below should be executed in x64 Native Tools Command Prompt.
mkdir build && cd build
cmake .. -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX="C:\Qt\5.15.2\msvc2019_64"
nmake && nmake install
This will install the compiled KDE module into the Qt installation path. You can install it elsewhere, but if you do, make sure you update PATH environment variable accordingly.
