On a pristine Ubuntu installation I get the cmake error:
CMake Error at qtgui/CMakeLists.txt:59 (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.
As I've told already this is also a MAC issue. The corresponding files are unfortunately not in the cmake default path
/usr/share/cmake-3.0/Modules but in
/usr/lib/x86_64-linux-gnu/cmake/. It is relatively easy to generate Makefiles nonetheless with:
cmake -DCMAKE_PREFIX_PATH=/usr/lib/x86_64-linux-gnu/cmake/ ..., however, I supposed at least on Linux we should have the appropriate directories as default paths. How is that handled on Debian?
