Pcl: CMake 3.17: The package name passed to `find_package_handle_standard_args` does not match the name of the calling package

[SunBlack]

I currently tested CMake 3.17(-rc1) on our build machine and currently we are getting following hints by CMake:

CMake Warning (dev) at /usr/local/share/cmake-3.17/Modules/FindPackageHandleStandardArgs.cmake:272 (message):
  The package name passed to `find_package_handle_standard_args` (PCL_COMMON)
  does not match the name of the calling package (PCL).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.

Maybe it helps to pass a max (3.16) version to cmake_minimum_required to fix it until we have time to really improve it. But currently I don't have time to test it.

Marking this as stale due to 30 days of inactivity. It will be closed in 7 days if no further activity occurs.

I think the issue is resolved in master. I'm using 3.17.2 and can't reproduce it

I was wrong

[SergioRAgostinho]

FYI: I remember also getting these warnings recently.

[amitrjaiswal1]

Still error exists. Anyone has solution for this ?

[SergioRAgostinho]

I believe the fix has been merged already. @larshg was it?

[larshg]

Not the fix I implemented. Mine was about Ensenso, LibUSB and one more I think.

This seems to be a warning when using PCL modules in downstream projects instead.

I got the same warning compiling a package, cartographer_ros, in catkin_ws in ROS running: $ catkin build for both PCL_COMMON and eigen!

[sebastian-freitag-pylot]

This is what I did to temporarily solve this issue and keep build output minimal and relevant:

CMakeLists.txt in my project:

(...)
# see here: https://github.com/PointCloudLibrary/pcl/issues/3680
# when this is fixed, we can remove the following 3 lines.
if(NOT DEFINED CMAKE_SUPPRESS_DEVELOPER_WARNINGS)
     set(CMAKE_SUPPRESS_DEVELOPER_WARNINGS 1 CACHE INTERNAL "No dev warnings")
endif()

find_package(PCL REQUIRED)

(...)

Seeing the same for rt:

  `_FOUND`) to follow a certain pattern.

@nccurry Your warning seems to come from a different project, not PCL. It appears you are compiling/using assimp? I suggest you open an issue there.

According to this cmake documentation (see note), the warning can be disabled by setting FPHSA_NAME_MISMATCHED. I think it is ok to do that because the function find_package_handle_standard_args is later also called for PCL, not only for the modules, so PCL_FOUND will be set.
