4 years ago @nonlinear1 I also do get the exact same warning on my machine all the time. I haven't looked into it in detail, but it is related to PCL, VTK, and potentially pcl_catkin.
Anyhow, it is not harmful and it has never impacted me so far.
When I use "catkin build mask_rcnn_ros depth_segmentation gsm_node -j4" to compile, I get errors: Warnings << pcl_ros:cmake /home/manifold/catkin_ws/logs/pcl_ros/build.cmake.004.log
CMake Warning at /home/manifold/catkin_ws/devel/share/pcl_catkin/cmake/pcl-extras.cmake:14 (find_package): By not providing "FindQVTK.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "QVTK", but CMake did not find one.
Could not find a package configuration file provided by "QVTK" with any of the following names:
Add the installation prefix of "QVTK" to CMAKE_PREFIX_PATH or set "QVTK_DIR" to a directory containing one of the above files.
