LAUNCHXL-F28379D: Error trying to add and use Endat22 Project. error #10234-D: Unresolved symbols Remain solution is required.

I tried to add the PM_endat22_BasicPosAcc_DelComp project function of BOOSTXL_POSMGR to the empty project. However, the #10234-D: unresolved symbol remains an error even though you added a library path to C2000 Linker -> File Search Path. I understand that the reason for the error is that there is no library. But I added a library. I wonder how the engineer who tried this created the project.
I want to know how to transplant the Endat project to another project.
Thank you.
