FindQt5 not provided for cmake

I used Homebrew to install qt4 in the past.
I uninstalled qt4, installed qt5 and tried building with cmake; Error posted below:

CMake Warning at CMakeLists.txt:97 (FIND_PACKAGE):
  By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "Qt5Widgets", but CMake did not find one.

  Could not find a package configuration file provided by "Qt5Widgets" with
  any of the following names:

    Qt5WidgetsConfig.cmake
    qt5widgets-config.cmake

  Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set
  "Qt5Widgets_DIR" to a directory containing one of the above files.  If
  "Qt5Widgets" provides a separate development package or SDK, be sure it has
  been installed.

  Found unsuitable Qt version "" from NOTFOUND, this code requires Qt 4.x

-- Configuring incomplete, errors occurred!

解决办法:

CMake bundles a FindQt4 module itself, but no FindQt5 module. The Qt5 cmake modules are provided by Qt5 itself, so you need to tell cmake where qt can be found:

cmake .. -DCMAKE_PREFIX_PATH=/usr/local/Cellar/qt5/5.3.1/
