Hello, I am using ROS noetic and trying to build some packages for Unitree A1.

However, this error shows up and the tree of directories seems right to me.

[ 84%] Building CXX object unitreerostoreal-3.2.1/unitreeleggedreal/CMakeFiles/lcmserver32.dir///unitreeleggedsdk-3.4.2/examples/lcmserver.cpp.o /home/user/catkinws/src/unitreeleggedsdk-3.4.2/examples/lcmserver.cpp:1:10: fatal error: unitreeleggedsdk/lcmserver.h: No such file or directory 1 | #include "unitreeleggedsdk/lcm_server.h" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated.

And the tree structure of directories is like
unitreeleggedsdk-3.4.2
- CMakeLists.txt
- examples - lcmserver.cpp
- include - unitreeleggedsdk - lcmserver.h where CMakeLists.txt, examples and include are peer directories.

Also, I edited CMakeLists.txt under unitreeleggedsdk-3.4.2 to contain
includedirectories(/home/user/catkinws/src/unitreeleggedsdk-3.4.2/include)

I really like to solve this problem, and thanks in advance....!!
