With CMake 3.11 I see a huge warning like this for every single build target, it's over 2400 lines total. Here's just one of the warnings:

CMake Warning at Tools/TestWebKitAPI/CMakeLists.txt:186 (add_library):
  Cannot generate a safe runtime search path for target
  TestWebKitAPIInjectedBundle because files in some directories may conflict
  with libraries in implicit directories:

    runtime library [libsoup-2.4.so.1] in /usr/lib64 may be hidden by files in:
      /home/mcatanzaro/Projects/WebKit/WebKitBuild/DependenciesGTK/Root/lib

  Some of these libraries may not be found correctly.

Of course, hiding system libraries is the entire purpose of JHBuild, so this is not very impressive. I don't think this is acceptable, so I consider CMake 3.11 to be fundamentally incompatible with JHBuild.

I'm seriously considering attempting to bootstrap CMake 3.10 in in the JHBuild to shut it up. I don't know what else we can do here asides ask for this to be reverted or stop using CMake altogether.
