question about using catch2 in makefile project

[Elnaz]

Hi,

I have a makefile project. this project involves files with determine hierarchy such as library, module, hardware abstraction layer and so on. 

I want to use catch2 for testing each function in every folder. 

my question is, where should I add catch.hpp to work and how?!

when I just copy and paste catch2.hpp to this folder of the project , I take this message : 

" You are opening a larg file. Scalability mode has been turned on for this editor to help improve performance.

Do you want to change scalability setting now?"

 I will be appreciated if someone help me.

Best regards,

Elnaz
