Issue Installing When Running Make in Build Folder

[Samberlance]

I follow the installation guide on my Mac running Monterey. However, when I get to the last step, running make in the created build folder after running qmake, I get the following message at the end:

23 warnings and 3 errors generated.
make: *** [obj/LEPTON_SDK.o] Error 1

Wondering what's causing this, and how it can be resolved, because when I try to open the GetThermal app, I get the following error:

You can’t open the application “GetThermal” because it may be damaged or incomplete.

Any help is appreciated!

Thanks.
