Inconnu CMake Qt5 commande

Je suis en train d'essayer de construire un projet à l'aide de CMake.
C'est le résultat que j'obtiens

CMake Warning at ext/quazip/CMakeLists.txt:4 (FIND_PACKAGE):
  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5" with any of
  the following names:

    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.


CMake Error at ext/quazip/CMakeLists.txt:19 (qt5_wrap_cpp):
  Unknown CMake command "qt5_wrap_cpp".

J'ai Qt Creator est installé et je ne sais pas pourquoi j'obtiens cette erreur.
J'ai regardé sur le web et ils ont dit que je devrais ajouter

set(QT_USE_QTXML true)
FIND_PACKAGE(Qt5)

après le #projet ext/quazip/CMakeLists.txt
Je l'ai fait, cependant j'ai toujours cette erreur des suggestions ?

Mise à jour:
J'ai donc ajouté ce qui suit à mon top niveau CMakeLists.txt

find_package( Qt5Core REQUIRED )
find_package( Qt5Widgets REQUIRED )
find_package( Qt5Gui REQUIRED )
find_package( Qt5OpenGL REQUIRED )
find_package( Qt5Multimedia REQUIRED )
find_package( Qt5WebKitWidgets REQUIRED )
find_package( Qt5Xml REQUIRED )

J'ai vidé le cache et ensuite configuré. À ce point, j'obtiens l'erreur suivante.

CMake Error at CMakeLists.txt:3 (find_package):
  By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5Core", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core" with any
  of the following names:

    Qt5CoreConfig.cmake
    qt5core-config.cmake

  Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
  "Qt5Core_DIR" to a directory containing one of the above files.  If
  "Qt5Core" provides a separate development package or SDK, be sure it has
  been installed.
