Error 16: The nature of this type of error should be a lack of lib files, just find and reasonable to add it. I started with CMake directly generated projects, all kinds of Lib has been configured, and CMake generated also did not error. But then I noticed that my own Pcl,cmake was 32, but when I automatically generated the project can only use x64 to run debugging, I guess my own software installed wrong, Baidu a bit, found that the original CMake generated files are consistent with the number of computer systems, My computer's 64, so it automatically generated suitable for 64-bit file engineering, so some lib even have been added, but still can't use. So I re-installed the PCL, replaced by 64, it can be used.

Summing up, the main reasons for encountering this problem are:

(1) Missing lib file, if you use CMake to automatically generate the project should also note that some third-party Lib may also be added.

(2) The properties of your PCL may differ from those of this computer. For example: If the PCL is 32-bit, the computer is 64-bit, generated with CMake, because the cmake generated by the project properties and the properties of their own computer is consistent, here CMake generated project is 64-bit. Therefore, some LIB files in the PCL may not be available.

Note: (1) (2) Two point is the problem that I have encountered during the installation process, and it is also solved. After solving such problems, you will find that the problems you struggle with for a few days are really simple questions that are easy to ignore. Point (3) also met, just found the relevant solutions on the Internet. A URL is attached.

(3) possible. h files do not have a corresponding hpp to implement

(4) Advice: Installation software is best to pay attention to the number of bits of your software installation. It is best to match the properties of your computer to avoid unnecessary errors.
