doesn't work on CPU only environment #52
Description
The documentation is misleading
https://github.com/intel/torch-ccl#install-from-source
here it says for cpu only backend python setup.py install
when its built on cpu only environment it looks for cuda related libraries and fails
below is the trace
-- Detecting CXX compile features - done
CUDA_TOOLKIT_ROOT_DIR not found or specified
-- Could NOT find CUDA (missing: CUDA_TOOLKIT_ROOT_DIR CUDA_NVCC_EXECUTABLE CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY)

or a Caffe2 dependent library, the next warning / error will give you more
