Dynamic link library construction problem

I think I need some help.
I'm still a student, but I'm a self-taught programmer.

I hope to build a dynamic link library suitable for arm architecture for application development on Huawei HarmonyOS system. I tried to get 61 files using (cmake && make) but I found I couldn't use them properly, maybe because I didn't add headers file? But shame, I'm not sure if it's a resource under /occt/src/, thanks in advance for your help,
