Keil MDK: Linker show error with a long relative libpath

Error L6002U showed this in the Build log:

linking...
.\Objects\WS_Passport_BL.axf: error: L6002U: Could not open file ..\..\..\..\..\..\..\..\..\..\AppData\Local\Arm\Packs_538\Keil\MDK-Middleware\7.16.0\Network\Lib\ARM\Net4_Dbg_CM3_L.lib: No such file or directory

I had checked the above relative path, it is correct, but the Linker couldn't see it.

I tried moving the current project folder to its parent directory, rebuild and it worked again!

So, my assumption is the package which has "long" relative path might cause this linker error.

Btw, these are some additional information about Middleware pack and Compiler toolchain:
