Summary0015888: No FindGTK3.cmake by default
DescriptionFor some reason, there is no FindGTK3 module yet, while FindGTK2 and FindGTK (last probably only used by 0000041:0000001.5 retrogrades) exist. It makes many developers re-invent FindGTK3 again and again, while it could be provided with CMake by default instead.
Steps To Reproduce
Additional InformationExamples of existing FindGTK3.cmake:
https://github.com/eiskaltdcpp/eiskaltdcpp/blob/master/cmake/FindGTK3.cmake [^] — a clone of FindGTK2.cmake
https://chromium.googlesource.com/external/Webkit/+/master/Source/cmake/FindGTK3.cmake [^] — PkgConfig-based solution

The GTK upstream provide pkg-config files for each of the GTK components. They could also provide CMake config files for use with find_package, as e.g the Qt upstream do for Qt5. Has a bug or patch been submitted to the GTK developers to implement this?

But it would be strange for GTK to provide configs for all existing build systems, while they use autotools for their source. On the other hand, the corresponding modules for GTK and GTK2 are included already—why not provide one for GTK3 as well?

Re 0015888:0040002: CMake packaging is explained here:

 https://cmake.org/cmake/help/v3.4/manual/cmake-packages.7.html [^]

The reason it is better for the files to come with the project is because they can then know exactly what other files come with them, how they were built, what is available, etc. They can be updated as needed for the project instead of being maintained in CMake. For example, Qt5 doesn't build with CMake but does provide CMake packaging files.

Plain find modules are a last resort because they have to guess everything and maintain lots of information about the corresponding packages.
