How to keep NVCC from generating compatibility for other 11 SM architectures? - cmake

Question

When I build PCL library on Jetson TX2 from source via CMAKE, I get the following debug logs among other msgs:
-- CUDA NVCC target flags:
-gencode;arch=compute_30,code=sm_30;
-gencode;arch=compute_35,code=sm_35;
-gencode;arch=compute_50,code=sm_50;
-gencode;arch=compute_52,code=sm_52;
-gencode;arch=compute_53,code=sm_53;
-gencode;arch=compute_60,code=sm_60;
-gencode;arch=compute_61,code=sm_61;
-gencode;arch=compute_70,code=sm_70;
-gencode;arch=compute_72,code=sm_72;
-gencode;arch=compute_75,code=sm_75
This means the binary files generated will be 10 times heavier than compared to single SM architecture. Also the compilation takes 10 times longer. sm_62 doesn't need to be included because its the architecture of base machine.
I don't want the compatibility. How can I avoid generating these compatibilties?
Here's the CMakeLists.txt--the same from PCL's repo.

I found a file which was causing the CMAKE to include 10 sm_arch in compatibility list. Here's the link. I will re-compile after editing the file for just 1 sm_arch and compare the size of binaries generated. – Anuj Patil Jan 22 at 18:10
So findCUDA was the culprit here. Editing the files to required sm_arch does the trick!
