--- Comment #20 from Sean Engelhardt <omniasoltempe...@yahoo.de> --- Hi. Unfortunately I cannot manage to Build Umbrello on my Arch Linux machine. Umbrello depends too much on KDE4 librarys, which are not available on Arch anymore. what I did: git clone https://gitlab.com/umbrello/test.git and then like the INSTALL told, cd umbrello mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=$HOME/umbrello -DCMAKE_BUILD_TYPE=Debug ../ The error is: --- CMake Error at pics/global/CMakeLists.txt:2 (kde4_install_icons): Unknown CMake command "kde4_install_icons". CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as cmake_minimum_required(VERSION 3.4) should be added at the top of the file. The version specified may be lower if you wish to support older CMake versions for this project. For more information run "cmake --help-policy CMP0000". This warning is for project developers. Use -Wno-dev to suppress it. -- Configuring incomplete, errors occurred! -- You are receiving this mail because: You are watching all bug changes.
