CPU Only build

Hi, can you give me the instructions to build CPU only, I don't have GPU. I changed CpuOnlyBuild to True and UseCuDNN to False but when I build **libcaffe** in VS2015, I meet some errors like that:

Severity Code Description Project File Line Suppression State
Error C2333 'caffe::ProposalLayer::Backward_gpu': error in function declaration; skipping function body (compiling source file ..\..\src\caffe\layers\proposal_layer.cpp) libcaffe D:\Caffe\caffe-windows\include\caffe\layers\proposal_layer.hpp 36

Severity Code Description Project File Line Suppression State

And when I build project **caffe:**
