Advises on makefile

[Hannes9]

Hi.

I got the following error message when executing the makefile on Colab:

...In file included from /usr/local/lib/python3.10/dist-packages/tensorflow/include/google/protobuf/generated_message_reflection.h:45,
                 from /usr/local/lib/python3.10/dist-packages/tensorflow/include/tensorflow/core/framework/full_type.pb.h:28,

make: *** [makefile:13: tf_nndistance_so.so] Error 1

My makefile looks like this and the pathes should be correct.

cuda_inc = /usr/local/cuda-12.0/include/
cuda_lib = /usr/local/cuda-12.0/lib64/
nvcc = /usr/local/cuda-12.0/bin/nvcc
tf_inc = /usr/local/lib/python3.10/dist-packages/tensorflow/include
tf_lib = /usr/local/lib/python3.10/dist-packages/tensorflow

all: tf_nndistance_so.so tf_approxmatch_so.so

tf_nndistance.cu.o: tf_nndistance.cu
	$(nvcc) tf_nndistance.cu -o tf_nndistance.cu.o -c -O2 -DGOOGLE_CUDA=1 -x cu -Xcompiler -fPIC

clean:
	rm -rf *.o *.so

I would appreciate it a lot, thanks !
