ARMCLANG compile TensorflowLiteMicro

I am developing a ML system based on Cortex-M4 in C language and combined tensorflow packages ( to my C project.

This package is writen in C++11. So, I use ARM Compiler V6.14 to build my C project.

Becuase Tensorflow package was writen in CC File not Cpp file so that Keil seems to reocognize CC file as C file, and it led to compiling error. So, I tried to converted all CC file in Tensorflow Packages to Cpp file, and Keil finally could build all of the Tensorflow Packages files in my project.

I want to know is there any way to let Keil MDK v5.37 recognize CC file as Cpp file? And I don't need to manually convert all CC file to Cpp File.

Thanks for your help!
