CC2652R: Symbol '$' could not be resolved error while using build variables

Hi,

I am trying to use some build variables in my application, however I get the following error

Symbol '$' could not be resolved

for e.g

Build Variable: SW_MAJOR_VER:3

Predefined symbol SW_BUILD=$(SW_MAJOR_VER)

SW_BUILD is used in the application code, However i get the following errors

1. Symbol 'SW_MAJOR_VER' could not be resolved

2. Symbol '$' could not be resolved

CCS 12

SDK 6.10 CC2652_1352

Any inputs would be helpful

Thanks
