Summary0014292: CMake does not add QT_NO_DEBUG definition for non-debug builds
DescriptionI 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.

No change required to CMake.

Qt5 comes with its own CMake config files maintained by Qt developers.
Any bugs in those files need to be submitted to them.

By the way, it has already been fixed for Release builds, and there is already a bug report for RelWithDebInfo builds.

Actually this is a CMake bug. The Qt5::Core IMPORTED target has the appropriate INTERFACE_COMPILE_DEFINITIONS, but CMake is not processing it correctly.

I've merged the fix-mapped-config-genex branch to next to fix that.
