Cmake + Boost 1.71 Undefined Reference in the library itself - c++

Question

I'm using CMAKE to build my project:
cmake_minimum_required(VERSION 3.14)
set (CMAKE_CXX_STANDARD 11)
project(saryxo_checker)
find_package( OpenCV REQUIRED )
find_package( Boost 1.71 REQUIRED COMPONENTS program_options filesystem system )
set(SOURCE_FILES
${CMAKE_CURRENT_LIST_DIR}/src/main.cpp
${CMAKE_CURRENT_LIST_DIR}/src/FeatureEvaluator.cpp
${CMAKE_CURRENT_LIST_DIR}/src/Converter.cpp
${CMAKE_CURRENT_LIST_DIR}/core/util.cpp)
include_directories(
${CMAKE_CURRENT_LIST_DIR}/include
${CMAKE_CURRENT_LIST_DIR}/core
${OpenCV_INCLUDE_DIR}
${Boost_INCLUDE_DIR})
add_executable(saryxo_checker ${SOURCE_FILES})
target_link_libraries(saryxo_checker ${OpenCV_LIBS} ${Boost_LIBRARIES})
However, it throws an error during linking. The errors are thrown INSIDE of Boost.

I tried building boost in debug mode, as I build my program in debug mode as well, but the error stays the same. What could it be?
