[BUG] cannot build on kubuntu 19.10 (CMAKE Error - Could NOT find KF5)

[HaukeW]

Describe the bug Hi! I cannot build hello on kubuntu 19.10.

To Reproduce

1. I installed the build dependencies (apt install ...) as written on the github-page
2. I followed the Manual Installation
3. I cannot complete the CMAKE-step.

Expected behavior compiling works

Additional files I added the logfile. CMakeOutput.log

Additional context distro: kubuntu 19.10

the terminal-output is this:

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

Two things you can try:

1) Install the missing dependencies:

sudo apt install build-essential libkf5config-dev libkdecorations2-dev libqt5x11extras5-dev qtdeclarative5-dev extra-cmake-modules libkf5guiaddons-dev libkf5configwidgets-dev libkf5windowsystem-dev libkf5coreaddons-dev gettext

2) Use the available PPA which should resolve build dependencies automatically:

sudo add-apt-repository ppa:krisives/kde-hello
sudo apt install kde-hello

Try either or both and see if it worked out for you.

@n4n0GH some dependencies seem to be missing from that list. I personally needed to do sudo apt install libkf5crash-dev kinit-dev kwin-dev in addition to the packages in that list (on KDE Neon 5.17). When installing from the PPA, "hello shaders" doesn't appear in the Desktop Effects settings.

@HaukeW try this: sudo apt install libkf5crash-dev kinit-dev libkf5globalaccel-dev libkf5kio-dev libkf5notifications-dev. These packages will provide the missing KF5 headers. If after that, you encounter an error concerning kwin effects, you might also need to install kwin-dev.

[n4n0GH]

Yes that is true, some deps are still missing from the guides. If you feel up to it, feel free to add them and issue a pull request so we can fill in the blanks.

Also @HaukeW you might want to check out this comment https://github.com/n4n0GH/hello/issues/41#issuecomment-562063700 which also lists needed build dependencies for KDE Neon which is essentially just Ubuntu. Those might als help you out as well.

Thanks everybody, that worked! I installed the dependencies you mentioned and building went through smoothly!
