I installed meshcat-cpp in the robot-install folder as follows

When I tried to run the example I got a runtime error. Indeed the visualizer is not able to find index.html because it is looking in the build folder build/share/MeshcatCpp

Unable to load the file in "/home/gromualdi/robot-code/meshcat-cpp/build/share/MeshcatCpp/misc/index.html"
terminate called after throwing an instance of 'std::runtime_error

still, this should not happen since I'm using https://github.com/ami-iit/reloc-cpp to locate the installation folder

Probably the example is using the build library instead of the installed one. See the comment in https://github.com/ami-iit/meshcat-cpp/pull/1#issuecomment-1412037838 .
