This release fixes the build with the upcoming Qt 5.6, which was failing like
this:
/usr/bin/c++ -O2 -pipe -fstack-protector -fno-strict-aliasing -Wnon-virtual-dtor -Wno-long-long -Wundef -Wcast-align -Wchar-subscripts -Wall -W -Wpointer-arith -Wformat-security -Woverloaded-virtual -fno-common -fvisibility=hidden -Werror=return-type -fvisibility-inlines-hidden -Wno-return-type-c-linkage CMakeFiles/cmTC_08ed6.dir/check_qt_visibility.cpp.o -o cmTC_08ed6 CMakeFiles/cmTC_08ed6.dir/check_qt_visibility.cpp.o:(.qtversion[qt_version_tag]+0x0): undefined reference to `qt_version_tag'
Most of the work was done by tcberner@.
