Here's the output of running
CMake in the Oxygen-transparent repo :
CMake Error at /usr/share/cmake-3.10/Modules/FindKDE4.cmake:60 (message): ERROR: Could not find KDE4 kde4-config
Where can I find that file ? Is it possible at all to install such an old program in newer KDEs ?
By the way I use KDE Neon dev edition 5.19.
Thanks in advance.
