[CMake] CMake 3.12 and changes in Visual Studio

[Hendrik Sattler]

Hi,

in CMake <= 3.11, the CMakeLists.txt file that contains the  
target-creating call, e.g. add_library(), was automatically added to  
the target as visible file in the Solution Explorer.

With CMake 3.12, this is suddenly not the case anymore.
Anybody knows what happened? On purpose or on accident?

Regards,

HS
