Laurent Rineau 471e7a93be Deal with Qt5 and Boost imported targets, when CGAL is imported
When CGAL_Qt5 or CGAL_Core targets are imported, then we need to call
`find_package(Qt5)` and `find_package(Boost)` to re-import the
targets of Qt5 or `Boost::thread`.

Otherwise, there is that CMake warning:

    CMake Warning (dev) at /mnt/testsuite/cmake/modules/CGAL_CreateSingleSourceCGALProgram.cmake:49 (add_executable):
      Policy CMP0028 is not set: Double colon in target name means ALIAS or
      IMPORTED target.  Run "cmake --help-policy CMP0028" for policy details.
      Use the cmake_policy command to set the policy and suppress this warning.

      Target "test_Min_circle" links to target "Boost::thread" but the target was
      not found.  Perhaps a find_package() call is missing for an IMPORTED
      target, or an ALIAS target is missing?
    Call Stack (most recent call first):
      CMakeLists.txt:22 (create_single_source_cgal_program)
    This warning is for project developers.  Use -Wno-dev to suppress it.

and then that link error:

    /usr/bin/ld: cannot find -lBoost::thread
