Can't use cmake generator expressions with QT_ANDROID_EXTRA_LIBS on macOS

In Qt6AndroidMacros.cmake

_qt_internal_android_format_deployment_path_property

calls

file(TO_CMAKE_PATH "${_path}" _path) 

to convert Windows paths to something that can be stored in a json file. This code causes issues on Unix systems when you pass generator expressions to QT_ANDROID_EXTRA_LIBS like $<TARGET_FILE:mylib::mylib> because cmake splits the path passed to TO_CMAKE_PATH base on the native PATH separator ";" [on windows] and ":" [on unix]. So on Unix systems it splits up the generator expressions. I would just wrap

file(TO_CMAKE_PATH "${_path}" _path)

with something like

if (CMAKE_HOST_WIN32)
    file(TO_CMAKE_PATH "${_path}" _path)
endif()

I would almost say this is a cmake bug but it's kinda not at the same time.
