cannot find libroscpp.so if installed node started as root

Hello, I have a node that I am supposed to start as root. Before I was using `catkin_make` to compile and I was sourcing devel/setup.bash and everything was working perfeclty. But today I tried to use `catkin_make install` and to source install/setup.bash` and this time my node is crashing. it says: error while loading shared libraries: libroscpp.so: cannot open shared object file: No such file or directory I also tried with another node (a dummy one) with the same CmakeLists. And this is really the combination between install and root that seems to be the problem. my launchfile: My CmakeLists: cmake_minimum_required(VERSION 2.8.3) project(bb_pigpio) add_compile_options(-std=c++11) find_package(catkin REQUIRED COMPONENTS roscpp std_msgs ) ################################### ## catkin specific configuration ## ################################### catkin_package( INCLUDE_DIRS include LIBRARIES bb_pigpio CATKIN_DEPENDS roscpp std_msgs ) ########### ## Build ## ########### ## Specify additional locations of header files include_directories( include ${catkin_INCLUDE_DIRS} ) ## Declare a C++ executable add_executable(${PROJECT_NAME}_node src/encoder_node.cpp src/encoder.cpp) add_dependencies(${PROJECT_NAME}_node ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS}) target_link_libraries(${PROJECT_NAME}_node ${catkin_LIBRARIES} pigpio ) ############# ## Install ## ############# install(TARGETS ${PROJECT_NAME}_node ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION} LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION} RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION} ) install(DIRECTORY include/${PROJECT_NAME}/ DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION} FILES_MATCHING PATTERN "*.hpp" ) install(DIRECTORY launch/ DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}/launch ) install(DIRECTORY config/ DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}/config ) Thanks for your help
