Solve CMake Error in CMakeLists.txt (FIND_PAKAGE):
CMake Error at src/CMakeLists.txt:5 (FIND_PACKAGE):
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.
-- Configuring incomplete, errors occurred!
- To help cmake find PCLConfig.cmake adding this line if you have installed ROS Kinetic:
set(PCL_DIR "/usr/lib/x86_64-linux-gnu/cmake/pcl/PCLConfig.cmake")
before find_package(PCL 1.3 REQUIRED COMPONENTS common io)
Or run loacate PCLConfig.cmake.

Bug fixed: When adding another visualization of pcl::visualization::CloudViewer.
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
visualOdometry: ../../src/xcb_io.c:179: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.
Aborted (core dumped)
We can see Note in The CloudViewer of pcl documents
The CloudViewer class is NOT meant to be used in multi-threaded applications! Please check the documentation on :pcl:
PCLVisualizer<pcl::visualization::PCLVisualizer>or read the PCLVisualizer tutorial for thread safe visualization.
The Viewer window does not be shutdown in visualOdometry.cpp.
To fix this bug: Add two line between } and pcl::io::savePCDFile(...).
