| Automatically link Qt executables to ``qtmain`` target on Windows. | |
| CMake 2.8.10 and lower required users of Qt to always specify a link | |
| dependency to the ``qtmain.lib`` static library manually on Windows. | |
| CMake 2.8.11 gained the ability to evaluate generator expressions | |
| while determining the link dependencies from ``IMPORTED`` targets. This | |
| allows CMake itself to automatically link executables which link to Qt | |
| to the ``qtmain.lib`` library when using ``IMPORTED`` Qt targets. For | |
| applications already linking to ``qtmain.lib``, this should have little | |
| impact. For applications which supply their own alternative WinMain | |
| implementation and for applications which use the QAxServer library, | |
| this automatic linking will need to be disabled as per the | |
| documentation. | |
| The ``OLD`` behavior for this policy is not to link executables to | |
| ``qtmain.lib`` automatically when they link to the QtCore ``IMPORTED`` target. | |
| The ``NEW`` behavior for this policy is to link executables to ``qtmain.lib`` | |
| automatically when they link to QtCore ``IMPORTED`` target. | |
