It turns out my cmake version is low. I have upgrade it to 3.14 and cmake .. is ok.
However,when I did "make " command, error still occurred.

from caffe-posenet.

It turns out that caffe in this project is slightly different with the official caffe. So we need to replace some files related to cudnn in caffe-posenet project.
Then I followed instructions of https://github.com/DRAhmadFaraz/PoseNet-Caffe.
Like
Replace ./include/caffe/util/cudnn.hpp with the latest version of cudnn in caffe, the corresponding cudnn.hpp. All files in ./include/caffe/layers that start with cudnn, such as cudnn_conv_layer.hpp. Replaced with the corresponding file of the same name in the latest version of caffe. Replace all files starting with cudnn, such as cudnn_lrn_layer.cu, cudnn_pooling_layer.cpp, cudnn_sigmoid_layer.cu, in ./src/caffe/layer with the corresponding file of the same name in the latest version of caffe.

finally worked!

hope this could help someone else.

Oh I finally make it.
I have made some mistakes in compiling this projects. So I am going to comment here for anyone in use.

This project have a caffe itself. So the first step is to do "[cmake ..] and [make all] and [make pycaffe] on your own.
I did not realise it until read some issue. So bad, hopefully project owner could write it somewhere in Readme file.

After I finish building this caffe, ~/.bashrc should add a line in order to specify the python this project is going to use. Here is my line.
export PYTHONPATH=$PYTHONPATH:/home/godu/Documents/caffe-posenet/python:$PYTHONPATH

Then you MUST change some lines in create_posenet_lmdb_dataset.py and test_posenet.py as the author mentioned.
Some users confront errors in this step.
You should notice that in the codes of python file, caffe_root ends with a "/".

This is one of my changes in 13 line of test_posenet.py file.

Make sure that caffe is on the python path:

caffe_root = '/home/godu/Documents/caffe-posenet/' # Change to your directory to caffe-posenet
import sys
sys.path.insert(0, caffe_root + 'python')
