I checked both distros I use and neither does. I suppose CMake itself should
create the toolchain file for multilib builds on Linux if this is a common
occurrence, but seems not to be the case.
The only toolchain file I can find in my system are the ones inside the Zephyr
and Chromium source codes. In fact, the one in qtwebengine/src/3rdparty/
chromium/third_party/boringssl/src/util/32-bit-toolchain.cmake is nearly
What is the one generated in qtbase/lib/cmake/Qt6/qt.toolchain.cmake for?
