Raspberry PI support...

I fear it is too complicated for me.
I installed all packages by running sudo ./preparehost-raspberryos.sh but I
still run into issues I don't have any clue to solve:
CMake Error at core/CMakeLists.txt:53 (find_package):
Could not find a package configuration file provided by "Qt5" (requested
version 5.9.0) 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.
When I sudo apt install kdevelop* I get further:
CMake Error at /usr/lib/arm-linux-gnueabihf/cmake/Qt5/Qt5Config.cmake:28
(find_package):
Could not find a package configuration file provided by
"Qt5WebEngineWidgets" with any of the following names:
Qt5WebEngineWidgetsConfig.cmake
qt5webenginewidgets-config.cmake
Add the installation prefix of "Qt5WebEngineWidgets" to CMAKE_PREFIX_PATH
or set "Qt5WebEngineWidgets_DIR" to a directory containing one of the
above
files. If "Qt5WebEngineWidgets" provides a separate development package
or
SDK, be sure it has been installed.
Call Stack (most recent call first):
core/CMakeLists.txt:66 (find_package)
It is probably not a digikam issue but some general stuff with qt. So for
this time I will give up. I do not feel comfortable absorbing developer
time for my personal qt-issues...
Anyway, thanks! Great software!!
