Fix Qt Dynamic Library Runtime Error

If a problem occurs with missing dynamic libraries when running a Qt program, you can try the following solutions:

1. Ensure that the dynamic library is installed: First confirm whether the missing dynamic library is already installed on the system. If it is not installed, you will need to install the corresponding dynamic library first.
2. To set the LD_LIBRARY_PATH environment variable: You can inform the system of the path of dynamic libraries by setting the LD_LIBRARY_PATH environment variable, for example: export LD_LIBRARY_PATH=/path/to/dynamic/library.
3. Check dynamic library dependencies using the ldd command: You can use the ldd command to view the dynamic libraries that an executable file depends on, then check if any necessary dynamic libraries are missing.
4. Set the dynamic library path in a Qt project by adding the LIBS parameter in the .pro file, for example: LIBS += -L/path/to/dynamic/library -lmylibrary.

By following the above methods, you should be able to resolve the issue of Qt not being able to find dynamic libraries at runtime. If the problem persists, you can try recompiling the Qt program or reinstalling Qt.
