Boost Dynamic Linking - c++

Question

I am aware this question was asked many times before, always ending with the same answer... add -DBOOST_LOG_DYN_LINK to your CMakeLists.txt file.
However, I've had this in my cmake for a long time and everything was linking without any problems. Now I decided to switch to Ubuntu 18.04 from 16.04 and update my projects one by one....
This is my cmake file:
cmake_minimum_required(VERSION 2.8.4)
project(FOO)
find_package(Boost REQUIRED COMPONENTS system timer filesystem log program_options unit_test_framework)
find_package(CGAL COMPONENTS Core)
find_library(OPEN_MESH_CORE_LIBRARY OpenMeshCore /usr/local/lib/OpenMesh REQUIRED)
find_library(YAML_CPP_LIBRARY yaml-cpp REQUIRED)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
find_package(PkgConfig REQUIRED)
pkg_check_modules(JSONCPP jsoncpp)
link_libraries(${JSONCPP_LIBRARIES})
include_directories(${JSONCPP_INCLUDE_DIRS})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -ffast-math -fopenmp -msse2 -march=native -W -Wall -std=c++11")
add_definitions(-DBOOST_LOG_DYN_LINK=1)
add_definitions(-DUNIT_TEST_DATA="${CMAKE_SOURCE_DIR}/data")
include( ${CGAL_USE_FILE} )
include( CGAL_CreateSingleSourceCGALProgram )
set(SOURCE_FILES
Foo1.cpp
Foo2.cpp
Foo3.cpp)
add_executable(FOO main.cpp ${SOURCE_FILES})
target_include_directories(FOO PRIVATE ${JsonCpp_INCLUDE_DIRS})
target_link_libraries(FOO ${OPEN_MESH_CORE_LIBRARY} ${Boost_LIBRARIES} ${YAML_CPP_LIBRARY} ${JSONCPP_LIBRARIES})
add_library(foo SHARED ${SOURCE_FILES})
target_link_libraries(foo ${OPEN_MESH_CORE_LIBRARY} ${Boost_LIBRARIES} ${YAML_CPP_LIBRARY} ${JSONCPP_LIBRARIES})
add_executable(tests test.cpp ${SOURCE_FILES})
target_include_directories(FOO PRIVATE ${JsonCpp_INCLUDE_DIRS})
target_link_libraries(tests ${OPEN_MESH_CORE_LIBRARY} ${Boost_LIBRARIES} ${YAML_CPP_LIBRARY} ${JSONCPP_LIBRARIES})
When compiled, it fails with known long list of problems, all related ending with a message
undefined reference to boost::log::v2_mt_posix::...
I am not a cmake ninja and it is very likely that I am doing something wrong, however, I can not find out what it is.
EDIT:
I have successfully tried to build it on a clean Ubuntu 16.04 with gcc 5 and boost 1.58
I have unsuccessfully tried to build it on a clean 18.04 with gcc7.1
and boost 1.65
I have unsuccessfully tried to build it on a clean 18.04 with gcc 5.5
and self compiled boost 1.58

All attempts followed an exactly the same procedure.

Cause of this problem wasn't in Boost or CMakeLists.txt. It was actually a problem of CGAL calling find_package(Boost) again somewhere in their use protocol when include( ${CGAL_USE_FILE} ) was invoked, and ended up overriding Boost_LIBRARIES with links to it's own components, completely omitting what I've found previously.
Here is the reported issue
Solution is somewhat dirty as I'didn't patch CGAL up. All it took was changing the order when i call include( ${CGAL_USE_FILE} ) and placing it at the top.
find_package(CGAL COMPONENTS Core)
include( ${CGAL_USE_FILE} )
find_package(Boost REQUIRED COMPONENTS system timer filesystem log
program_options unit_test_framework)
Please NOTE that this is a quick fix and can result in further problems such as overriding Boost components required by CGAL!
