Summary:                    CMake does not add QT_NO_DEBUG definition for
non-debug builds
Description: 
I created Qt5 CMake project and use the code like the following:

cmake_minimum_required(VERSION 2.8.11)
find_package(Qt5Core REQUIRED)
target_link_libraries(${PROJECT_NAME} Qt5::Core)

The problem is that CMake does not defines QT_NO_DEBUG for release build, like
qmake does. If I build qml-plugin, I can't use release build of it, because Qt
takes it for debug build and I get the following error:

"The plugin uses incompatible Qt library. (Cannot mix debug and release
libraries.)"

The workaround is simple:

if(NOT CMAKE_BUILD_TYPE STREQUAL "Debug")
    add_definitions(-DQT_NO_DEBUG)
endif()

It works, but I think this should be done in CMake.
