src folders inside SDK projects.

Well I didn’t know how to describe it in the title but what I am looking is this ::

Currently for making a new project in CUDA, I copy a template project from the CUDA SDK and change the codes/codefiles/Makefile appropriately. But till now I have all of my codefiles in the same folder. src/myCUDA_project/. Is there any way I could have my codefiles inside folders ? Like this ::

src/myCUDA_project/Code1Folder/Code1.h

src/myCUDA_project/Code1Folder/Code1.cpp

src/myCUDA_project/Code1Folder/Code1_kernels.cu

src/myCUDA_project/Code2Folder/Code2.h

src/myCUDA_project/Code2Folder/Code2.cpp

src/myCUDA_project/main.cpp

I have tried it with having the Makefile set as ::

CUFILES		  :=

					  Code1Folder/Code1_kernels.cu

CCFILES		  := 

					 main.cpp \

					 Code1Folder/Code1.cpp \

					 Code2Folder/Code2.cpp

CCDEPS		 :=

					 Code1Folder/Code1.h \

					 Code2Folder/Code2.h

But I receive ::

make: *** No rule to make target `obj/x86_64/release/Code1_kernels.cu.o', needed by `../../bin/linux/release/myCUDA_project'.  Stop.
