Joint CMake link library built from object libraries

Question

I can not start my cmake project. He should create a library (Core), and then add this library to a new shared library. The problem is that the resulting library does not seem to reference the executable correctly.

fatal error: JNF_NEAT/body.h: No such file or directory

I have a CMake project that is structured as follows:

root
  -> CMakeLists.txt
  -> Core/
     -> CMakeLists.txt
     -> Sources/
  -> Examples/
     -> CMakeLists.txt
     -> Example1/
        -> CMakeLists.txt
        -> Sources/

root / CMakeLists.txt

cmake_minimum_required(VERSION 3.2.2)
project(JNF_NEAT)

set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/out/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/out/examples)

add_subdirectory(Core)

add_library(JNF_NEAT SHARED $<TARGET_OBJECTS:Core>)
target_link_libraries(JNF_NEAT -lstdc++fs)

add_subdirectory(Examples)

root / kernel /CMakeLists.txt

file(GLOB SOURCES Sources/*.cpp Sources/*.h)
add_library(Core OBJECT ${SOURCES})

root / Examples / CMakeLists.txt

add_subdirectory(XOR)

root / Examples / XOR / CMakeLists.txt

include_directories(../../out/lib)

file(GLOB SOURCES Sources/*.cpp Sources/*.h)
add_executable(XOR_EXAMPLE ${SOURCES})
target_link_libraries(XOR_EXAMPLE JNF_NEAT)

All source code is available here .

Edit # 1

I tried to install target_include_directories(XOR_EXAMPLE BEFORE PUBLIC ../../out/lib)beforetarget_link_libraries

I also tried installing include_directories(out/lib)in the majority of external CMakeLists.txt

Edit # 2

On Linux, this error .
