Include mongocxx drivers with Cmake results with undefined methods on Ubuntu - linux

Question

I have an issue with linking libmongocxx in my project.
I am using CMAKE to link the library and I am running Ubuntu 17.10.
Here is my CMakeLists.txt :
cmake_minimum_required(VERSION 3.9)
project(web_service_cpp)
SET(CMAKE_CXX_STANDARD 14)
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR}/bin)
set(LIBRARY_OUTPUT_PATH ${CMAKE_BINARY_DIR}/lib)
find_package(Boost REQUIRED)
find_package(Hana REQUIRED)
find_package(libmongocxx REQUIRED)
find_package(libbsoncxx REQUIRED)
add_library(libmongocxx INTERFACE IMPORTED)
set_property(TARGET libmongocxx PROPERTY
INTERFACE_INCLUDE_DIRECTORIES ${libmongocxx_INCLUDE_DIR})
add_library(boost INTERFACE IMPORTED)
set_property(TARGET boost PROPERTY
INTERFACE_INCLUDE_DIRECTORIES ${Boost_INCLUDE_DIR})
include_directories(${LIBMONGOCXX_INCLUDE_DIR})
include_directories(${LIBBSONCXX_INCLUDE_DIR})
include_directories("/usr/local/include/mongocxx/v_noabi")
include_directories("/usr/local/include/bsoncxx/v_noabi")
include_directories("/usr/local/include/libmongoc-1.0")
include_directories("/usr/local/include/libbson-1.0")
include_directories("/usr/local/lib")
include_directories("${PROJECT_SOURCE_DIR}")
set(SOURCE_FILES src/main.cpp
src/cMqttService.cpp
src/cMongoDB.cpp
src/cRepository.cpp)
set(HEADER_FILES include/cRepository.h
include/cMqttService.h
include/cMongoDB.h
include/main.h)
add_executable(web_service_cpp
${HEADER_FILES}
${SOURCE_FILES})
target_link_libraries(web_service_cpp ${LIBMONGOCXX_LIBRARIES})
target_link_libraries(web_service_cpp ${LIBBSONXX_LiBRARIES})
I find it weird that I am getting this error since it use to work on macOS :

I am open to suggestions!
Thank you for your help in advance.

I found the solution to my problem. It is caused by all those hard coded strings that I used back on macOS.
