<![CDATA[Can't use libs after included]]>Hello,
I am currently using QT Creator to create my own application. I created Project and chose Cmake
This is my Cmakelist.txt:

cmake_minimum_required(VERSION 2.8)

project(RS15)
find_package(PCL 1.8 REQUIRED)

set (IMGUI_INCLUDE_DIRS "/home/nmhieu_brycenvn/Qt5/Test_File/imgui")
set (IMGUI_DEFINITIONS "/home/nmhieu_brycenvn/Qt5/Test_File/imgui")

include_directories(${IMGUI_INCLUDE_DIRS})
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
add_definitions(${IMGUI_DEFINITIONS})

add_executable(${PROJECT_NAME} "main.cpp")
target_link_libraries (RS15 ${PCL_LIBRARIES})

Not sure if I wrote Cmake correctly? I searched for hours to write it down, but the ImGui (a separated library) library couldn't be used, while PCL was fine.

Can someone help me know how to include a separated library in file Cmake?
Thanks for reading!!

You need to extend this line to link properly:

target_link_libraries (RS15 ${PCL_LIBRARIES})

i added this to the cmakelist

set (IMGUI_SOURCE "/home/nmhieu_brycenvn/librealsense/third-party/imgui")
target_include_directories(RS15 PUBLIC ${IMGUI_SOURCE})

But its still not working, am I wrong something?

target_link_libraries (RS15 ${PCL_LIBRARIES})

You don't link against ImGui libs
