CMake: Fix for QT 5.7 overwriting -std=c++1y flag

In QT 5.7 they added a new check for CXX features which appends a minimum
required standard to the CXX_FLAGS. Because we were writing the flag
directly previously, cmake assumed it needed to add a c++11 flag to the
build. This tells cmake to use c++14 on every build.
