kwin requires qt5.7.0

[Allen Winter]

I thought Qt5.6 was the minimum required?
Just asking.  I don't care that much but I need to install Qt5.7 , which of course I can do.

when running CMake on kwin I get:
CMake Error at CMakeLists.txt:20 (find_package):
  Could not find a configuration file for package "Qt5" that is compatible
  with requested version "5.7.0".

  The following configuration files were considered but not accepted:

    /usr/lib64/cmake/Qt5/Qt5Config.cmake, version: 5.6.2
