Hardcoded Qt6_DIR path.

[ColePoppleton]

The line set(Qt6_DIR "C:/Qt/6.9.0/mingw_64/lib/cmake/Qt6") contains a hardcoded path to the Qt 6 installation. This will prevent the project from being built on other machines without modification. Remove this line. CMake's find_package command can usually locate Qt 6 automatically if Qt is properly installed and configured in the system's environment. If a hint is needed, consider using a CMake variable that can be set by the user when configuring the project.
