Is there a way to load and index a gmake project to CLion?

So I am coding on my PC but the code is located on the company local cloud 
The build process is running on a dedicated linux machine using gmake. 

I am working on a pretty big C/C++ application 
Most of the code sits under ./src ./include (and others dirs as well) 

so far from what i've seen - in order to allow indexing/call hierarchy and find declarations i need to define Toolchine and CMake 
Is there a way to use CLion as a "stupid" idea without forcing it into a CMake project? 
I want to use CLion as my coding platfom but i want to make the build process external to the IDEA
