Can't Install Wireshark due to Qt6Core5Compat?
CMake Error at CMakeLists.txt:1243 (find_package): By not providing "FindQt6Core5Compat.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Qt6Core5Compat", but CMake did not find one.
Could not find a package configuration file provided by "Qt6Core5Compat" with any of the following names:
Qt6Core5CompatConfig.cmake
qt6core5compat-config.cmake
Add the installation prefix of "Qt6Core5Compat" to CMAKE_PREFIX_PATH or set "Qt6Core5Compat_DIR" to a directory containing one of the above files. If "Qt6Core5Compat" provides a separate development package or SDK, be sure it has been installed.
