目录中：/home/edward/git/libs/openpose2021/include/openpose_private/tracking/pyramidalLK.hpp
所以怎么会找不到这个文件呢？一时也不知道如何修改，所以直接修改代码，用绝对路径：
#include </home/edward/software/openpose/include/openpose_private/tracking/pyramidalLK.hpp>
其他类似问题也依靠这个来解决。---有没有大牛可以帮忙解答一下？
几乎所有的都和.cu文件相关。--
找不到头文件caffe/blob.hpp：
home/edward/git/libs/openpose2021/src/openpose/core/arrayCpuGpu.cpp:3:14: fatal error: caffe/blob.hpp:
这个是在 Caffe_INCLUDE_DIRS 配置上需要修改：
/home/edward/git/libs/openpose2021/3rdparty/caffe/include
找不到头文件caffe/proto/caffe.pb.h：
In file included from /home/edward/git/libs/openpose2021/src/openpose/core/arrayCpuGpu.cpp:3:
/home/edward/git/libs/openpose2021/3rdparty/caffe/include/caffe/blob.hpp:9:10: fatal error: caffe/proto/caffe.pb.h: No such file or directory
#include "caffe/proto/caffe.pb.h"
这个问题和以前的问题还不一样，这些都是build的时候出现的头文件。这个文件在：
/home/edward/git/libs/openpose2021/3rdparty/caffe/build/include/caffe/proto/caffe.pb.h
也先直接用绝对路径来解决。
也可以在cmake-gui 中， Caffe_INCLUDE_DIRS 配置为
/home/edward/git/libs/openpose2021/3rdparty/caffe/include;/home/edward/git/libs/openpose2021/3rdparty/caffe/build/include
连接错误undefined reference to symbol \'cudaFree@@libcudart.so.11.0\'
这个是在：
[ 97%] Building CXX object examples/tests/CMakeFiles/resizeTest.bin.dir/resizeTest.cpp.o
也就是一个测试例子，看看能不能删除这个例子。
/usr/bin/ld: CMakeFiles/resizeTest.bin.dir/resizeTest.cpp.o: undefined reference to symbol \'cudaFree@@libcudart.so.11.0\'
/usr/bin/ld: /usr/local/cuda/lib64/libcudart.so.11.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
cudaFree symbol is defined in libcudart.so. It should be located in /usr/local/cuda/lib with a default install.(DSO is a dynamic shared object or a shared library)
解决办法：直接把这个例子全部注释掉，幸好只有一个例子受到影响
执行文件时出现No OpenGL support：
./build/examples/openpose/openpose.bin --video examples/media/video.avi
当cmake和make编译均通过之后，执行文件时出现该错误
