`make all` fails for .build_release/tools/convert_imageset.bin

Hi there,

for me compilation fails with the following error message:

CXX/LD -o .build_release/tools/convert_imageset.bin
.build_release/lib/libcaffe.so: undefined reference tocaffe::SampleLayer::Forward_gpu(std::vector<caffe::Blob, std::allocator<caffe::Blob> > const&, std::vector<caffe::Blob, std::allocator<caffe::Blob> > const&)
.b uild_release/lib/libcaffe.so: undefined reference to caffe::SampleLayer::Forward_gpu(std::vector<caffe::Blob, std::allocator<caffe::Blob> > const&, std::vector<caffe::Blob, std::allocator<caffe::Blob> > const&)
collect2: error: ld returned 1 exit status
Makefile:564: recipe for target '.build_release/tools/convert_imageset.bin' failed
make: *** [.build_release/tools/convert_imageset.bin] Error 1

I was able to circumvent the error by declaring the mentioned function in ´sample_layer.cpp´, but that does not seem to be a real solution. Is this a known issue? I am just using the CPU for now, but would eventually like to run the model on a GPU aswell.
