appear error : CMake Error at CMakeLists.txt:75 (set_target_properties): Property INTERFACE_LINK_LIBRARIES may not contain link-type keyword "optimized". The INTERFACE_LINK_LIBRARIES property may contain configuration-sensitive generator-expressions which may be used to specify per-configuration rules.

Maybe the version of cmake is too old. I recommend upgrading your ubuntu as Ubuntu 18.04 is no longer supported and it is dangerous to keep using it.

This question was solved by upgrade the version of PCL, I tested PCL1.13.1 which was working properly.

Just to make other people's lives easier, I had to change the CMakeLists.txt a bit to get this to work after I installed pcl from source (because I think the newest version of PCL is not available through apt). It was pretty simple though, I just changed the find_package line that was supposed to find PCL to: find_package(PCL 1.13.0.99 EXACT REQUIRED)
