CMake Error when compiling set_vel_plugin

[muronglindong]

Hello, I'm learning Setting Velocity on Links And Joints, but when I downloaded all the codes and compiled the set_vel_plugin as the tutorials guiding, there exists a cmake error:

mu@mu-TM1703:~/gazebo_tutorials-master/set_velocity/examples/set_vel_plugin/build$ cmake ..

How to solve this problem?
I use ubuntu 20.04, gazebo 11, thank you!

Seems to me a problem related to the installation of Simbody libraries. Could you please remove them (apt-get remove .*simbody.*, install them again (apt-get install libsimbody-dev), remove your CMakeCache.txt file and try to run cmake again to check if it is a problem on your local system?

I got the same error, but nothing changed after reinstalling libsimbody-dev (libsimbody-dev is already the newest version (3.6.1+dfsg-7build1))
