ERROR message as:

CMake Warning at CC/CMakeLists.txt:26 (message):
  CCLib configured without parallel algorithm capabilities - see
  COMPILE_CC_CORE_LIB_WITH_TBB

CMake Error at cmake/CMakeExternalLibs.cmake:18 (find_package):
  By not providing "FindQt5PrintSupport.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "Qt5PrintSupport", but CMake did not find one.

  Could not find a package configuration file provided by "Qt5PrintSupport"
  with any of the following names:

    Qt5PrintSupportConfig.cmake
    qt5printsupport-config.cmake

  Add the installation prefix of "Qt5PrintSupport" to CMAKE_PREFIX_PATH or
  set "Qt5PrintSupport_DIR" to a directory containing one of the above files.
  If "Qt5PrintSupport" provides a separate development package or SDK, be
  sure it has been installed.

解决方案：

修改cmake/CMakeExternalLibs.cmake文件，添加一行内容：

set (CMAKE_PREFIX_PATH "/usr/local/Cellar/qt/5.10.1/lib/cmake")

/usr/local/Cellar/qt/5.10.1/lib/cmake 为对应的QT安装路径

修改后重新cmake .. 即可成功。
