Hello. I have a C++ node working with openCV and I want to add a non-ROS library to my package. The library is here. I don't want to install the whole external package, so I just stored the slic.cpp and slic.h files in the src directory of my package. I included the libraries as is done in the demo.cpp. When I modify the CMakeLists.txt of my package as I found in several tutorials, and I compile with catkin_make I get these errors:
/home/spyros/catkin_ws/src/door_detector_1/src/slic.cpp:682:6: error: ‘_ASSERT’ was not declared in this scope
_ASSERT( y < m_height && x < m_width && y >= 0 && x >= 0 );

I think I'm doing something wrong in my CMakeLists.txt:
cmake_minimum_required(VERSION 3.0.2)
project(door_detector_1)
add_compile_options(-std=c++11)
find_package(catkin REQUIRED COMPONENTS
roscpp
rospy
std_msgs
message_generation
cv_bridge
)
find_package(GTSAM REQUIRED)
find_package(OpenCV 3.2.0 REQUIRED)
SET(BUILD_SHARED_LIBS on)
catkin_package(
INCLUDE_DIRS include
LIBRARIES slic
CATKIN_DEPENDS roscpp rospy std_msgs message_runtime cv_bridge image_transport
# DEPENDS slic
)
include_directories(${GTSAM_INCLUDE_DIR} ${catkin_INCLUDE_DIRS} src)
include_directories(${OpenCV_INCLUDE_DIRS})
add_library(slic src/slic.cpp)
target_link_libraries(slic ${OpenCV_LIBRARIES})
add_executable(vision_trials src/vision_trials.cpp)
target_link_libraries(vision_trials gtsam ${catkin_LIBRARIES})
target_link_libraries(vision_trials ${OpenCV_LIBRARIES})
add_dependencies(vision_trials door_detector_1_generate_messages_cpp)
target_link_libraries(vision_trials slic)
What am I doing wrong here? I'm confused with the different modifications needed in CMakeLists.txt in different cases (adding non-ROS library, adding a library used in a different package etc).
I use ubuntu 18.04, C++11 and ROS melodic.
Any feedback is appreciated. Thanks in advance.
