My tailing-edge Leap 42.3 VM seems to be stuck on 5.6
The main check in CMakeLists.txt appears to be this:
if (Qt5Widgets_VERSION VERSION_LESS 5.3)
message(FATAL_ERROR "Qt 5.3 or later is required.")
endif()
if (Qt5Widgets_VERSION VERSION_GREATER 5.6
AND (CMAKE_COMPILER_IS_GNUCC OR CMAKE_C_COMPILER_ID MATCHES
"Clang"))
# Qt 5.7 and later require C++ 11.
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
endif()
There are some other platform-specific checks (Mac).
I don't know what else goes into the decision to move the Qt version
required onwards - if it moves forward I will create a new VM.
