CMake problem
GeographicLibConfig.cmake
The find package
find_package(GeographicLib REQUIRED)
in cmake fails, as the file GeographicLibConfig.cmake is not found.
This can be fixed by renaming the provided file FindGeographicLib.cmake by
cd /usr/share/cmake/geographiclib sudo ln -s FindGeographicLib.cmake GeographicLibConfig.cmake
XKB
Missing library, and CMake complains:
-- Could NOT find XKB (missing: XKB_LIBRARY XKB_INCLUDE_DIR) (Required is at least version "0.5.0")
The solution was to install
sudo apt install libxkbcommon-dev
This occurred on Raspberry Pi 5 using 64bit default OS.
