SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. pip install pybind11 2. cmake .. OBSERVED RESULT CMake Error at CMakeLists.txt:38 (find_package): By not providing "Findpybind11.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "pybind11", but CMake did not find one. Could not find a package configuration file provided by "pybind11" with any of the following names: pybind11Config.cmake pybind11-config.cmake Add the installation prefix of "pybind11" to CMAKE_PREFIX_PATH or set "pybind11_DIR" to a directory containing one of the above files. If "pybind11" provides a separate development package or SDK, be sure it has been installed. EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/KDE Plasma: kde neon KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION
Installing pybind11 from source or from your distribution should fix this. When installed from pip, it doesn't seem to be in the default cmake package path.
Closing this, since it's just a matter of installing the right package from the distribution.
