CMake doesn't add dependency libraries to the project files - visual-studio

Question

I am writing a simple example code using pcl just as the link
http://pointclouds.org/documentation/tutorials/writing_pcd.php.
Even though I follow the link, Visual studio reports link errors.
The reason is that pcl depends on boost library and cmake doesn't
add boost library to the project setting files of visual studio.
If I add boost library with the following line, everything will be OK.
target_link_libraries(progname ${Boost_LIBRARIES})
Why doesn't CMake handle this? Is there a better solution?
CMake: 3.13.2,
Visual studio: Community 2017
PCL: PCL-1.9.1-AllInOne-msvc2017-win64.exe
Edit:
CMakeLists.txt
cmake_minimum_required(VERSION 2.6 FATAL_ERROR)
project(MY_GRAND_PROJECT)
set(Boost_DEBUG ON)
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost 1.45.0)
find_package(PCL 1.9.1 REQUIRED COMPONENTS common io)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
add_executable(pcd_write_test pcd_write.cpp)
target_link_libraries(pcd_write_test ${PCL_COMMON_LIBRARIES} ${PCL_IO_LIBRARIES} ${Boost_LIBRARIES})

According to the PCLConfig.cmake script in the official repo, Boost libraries are appended to the PCL_LIBRARIES variable. (This is performed near the end of the script).
So, for automatically link with Boost libraries when use PCL, you need to use PCL_LIBRARIES variable for linking, not PCL_<comp>_LIBRARIES variables.
I don't know, whether given behaviour is intended or not. If you assume that Boost libraries should be part of PCL_<comp>_LIBRARIES variables too, then you may fill a bug-report about that.
