build qt6.6+emscripten3.1.37+vtk9.3 failed

Hello, I am tring to build VTK with QT in Emscripten but the build status is failed.

• vtk: I am using master branch at commit 45dc32e949
• qt: version is 6.6.0. qt is supported to be build on emscripten https://doc-snapshots.qt.io/qt6-dev/wasm.html
• emscritpen: 3.1.37
