Seems to be the same problem as in this issue: https://github.com/PointCloudLibrary/pcl/issues/4620 Please see there for suggestions

Hello, thank you for reminding me, but my pcl was not installed through vcpkg. I downloaded PCL-1.12.1-AllInOne-msvc2019-win64.exe directly to install it

The person who opened that issue also used the all-in-one installer. I quote:

when using the all one installer. I found an issues with flann

So please, check that issue page again, especially the comment from larshg. Also, if you can't make it work with the all-in-one installer, have you tried removing that and using vcpkg instead?

Thanks for reminding me, but it didn't solve my problem

So what exactly did you try? Did you try using vcpkg instead of the all-in-one installer? Or did you try the guide linked in larshg's comment:

For a guide using All-In-On-Installer please look at the following: https://github.com/PointCloudLibrary/pcl/issues/4462

Please describe more precisely what you tried and what the result was. If you are so vague, I don't know what solution I should recommend to you.

I tried to install pcl with vcpkg. The installation was successful, but the following error was prompted when referencing pcl in cmakelists.txt CMakeLists.txt:47: error: By not providing "FindPCL.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "PCL", but CMake did not find one. Could not find a package configuration file provided by "PCL" with any of the following names: PCLConfig.cmake pcl-config.cmake Add the installation prefix of "PCL" to CMAKE_PREFIX_PATH or set "PCL_DIR" to a directory containing one of the above files. If "PCL" provides a separate development package or SDK, be sure it has been installed.

Have you suppliee this to cmake when calling it: DCMAKE_TOOLCHAIN_FILE=[path to vcpkg]/scripts/buildsystems/vcpkg.cmake ?

My project is QT and the compilation method is camke. How do I configure DCMAKE in camkelists.txt TOOLCHAIN FILE？

This is the code referencing PCL library in my CMakeLists.txt set(CMAKE_TOOLCHAIN_FILE D:/vcpkg/vcpkg/scripts/buildsystems/vcpkg.cmake) find_package(PCL 1.12 REQUIRED COMPONENTS common io) include_directories(${PCL_INCLUDE_DIRS}) link_directories(${PCL_LIBRARY_DIRS}) add_definitions(${PCL_DEFINITIONS}) link_directories(test ${PCL_LIBRARY_DIRS})

But the same error will be reported G:\Project\zxtx_autocar\src\CMakeLists.txt:47: error: By not providing "FindPCL.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "PCL", but CMake did not find one.
