fatal error: caffe/caffe.hpp: No such file or directory

には、

Proto-files
Now protobuf files ARE NOT copied to <caffe_root>/include/caffe/proto anymore. Instead they are generated to <build_dir>/include/caffe/proto. Know one may include old headers, but this is interest rates to payback of technical debt appeared due to incorrect original cmake scripts design. Also removed them from .gitignore

とあるので、

set(SSD_CAFFE_PATH "$ENV{HOME}/ssdcaffe/distribute")

を

set(SSD_CAFFE_PATH "$ENV{HOME}/ssdcaffe/build:$ENV{HOME}/ssdcaffe/distribute")

に変える。
