Jom doesn't ship a Windows arm64 binary, you will have to build it 
yourself. See Index of /official_releases/jom 
<https://download.qt.io/official_releases/jom/>

For best performance I recommend using native arm tools. ninja 
<https://github.com/ninja-build/ninja/releases/>, cmake 
<https://github.com/kitware/cmake/releases>.

Please do use the *Windows arm64 Qt SDK installer 
<https://download.qt.io/official_releases/online_installers/qt-online-installer-windows-arm64-online.exe>*. 
This will install the native arm64 version of Qt, Qt Creator, ninja, and 
cmake.

You will have to install Visual Studio 2022, since that's the first 
version that has native arm64 compilers.

If you want to have an arm64 mingw toolchain, use llvm-mingw 
<https://github.com/mstorsjo/llvm-mingw/releases>. You will have to 
configure the toolchain manually and build Qt yourself, since windows 
arm64 mingw is not supported by Qt SDK.

Cheers,
Cristian.
