Comment compiler KanColleTool ?

J'ai téléchargé le KanColleTool de GitHub avec cette commande :

git clone --recursive https://github.com/KanColleTool/KanColleTool.git KanColleTool.git

Cependant, lorsque j'exécute :

cmake -DCMAKE_INSTALL_PREFIX=/usr

...ça arrive :

CMake Error at viewer/src/CMakeLists.txt:28 (find_package):
By not providing "FindQt5WebKitWidgets.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"Qt5WebKitWidgets", but CMake did not find one.

Could not find a package configuration file provided by "Qt5WebKitWidgets"
with any of the following names:

Qt5WebKitWidgetsConfig.cmake
qt5webkitwidgets-config.cmake

Add the installation prefix of "Qt5WebKitWidgets" to CMAKE_PREFIX_PATH or
set "Qt5WebKitWidgets_DIR" to a directory containing one of the above
files.  If "Qt5WebKitWidgets" provides a separate development package or
SDK, be sure it has been installed.
