solved a missing dependacy

cmake -B build -S . -GNinja -DUSE_PLASMAPKG=ON CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage -- Configuring incomplete, errors occurred!

solution "pacman -S ninja"

Solution for Fedora: sudo dnf install ninja-build ...build

Thanks for posting this, one step farther now to getting this working for me.

building on manjaro for digital signage solution, had that same error and installed ninja, but now it gets to ~10-11/174ish (i can't recall the numbers) and freezes. the entire desktop slows down to a crawl and the clock bottom right gets more and more wrong. eventually freezing entirely. possibly an issue with my limited ram (3.8GB intel NUCs) as mentioned here

trying this on steam deck, your solution helped but now i get this.

(deck@steamdeck wallpaper-engine-kde-plugin)$ cmake -B build -S . -GNinja -DUSE_PLASMAPKG=ON -- The C compiler identification is unknown -- The CXX compiler identification is unknown CMake Error at CMakeLists.txt:9 (project): No CMAKE_C_COMPILER could be found.

Tell CMake where to find the compiler by setting either the environment variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.
