Unable to find headers in a project - c++

Question

I have difficulties with CMakeLists file. I have done pretty much the same in my other project, so i know the paths are correct. But i tried to make it a bit more pretty so I created a new CMakeLists file.
Now my project fails to find the headers.
Anyone see what I have missed?
Here is my CMakeLists file:
project("Test Cell Camera")
set(VERSION_MAJOR 0)
set(VERSION_MINOR 1)
set(VERSION_PATCH 0)
set(CMAKE_CXX_STANDARD 17)
set(lib_TARGET tcc)
set(exec_TARGET tcc_exe)
set(test_TARGET tcc_test)
set(SRC_DIR "${CMAKE_CURRENT_SOURCE_DIR}/src")
set(INCLUDE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/include")
set(TESTS_DIR "${CMAKE_CURRENT_SOURCE_DIR}/tests")
set(LIBS_DIR "${CMAKE_CURRENT_SOURCE_DIR}/libs")
set(CONFIG_DIR "${CMAKE_CURRENT_SOURCE_DIR}/config")
set(main_SRC_FILE "${SRC_DIR}/main.cpp")
include_directories(
${SRC_DIR}
${INCLUDE_DIR}
"C:/Program Files/Basler/pylon 5/Development/include" # Basler
)
file(GLOB lib_INCLUDE "${INCLUDE_DIR}/*/*.h")
file(GLOB lib_SRC "${SRC_DIR}/*.cpp")
list(FILTER lib_SRC EXCLUDE REGEX ${main_SRC_FILE})
file(GLOB main_SRC ${main_SRC_FILE})
# Add all test sources
file(GLOB test_SRC "${TESTS_DIR}/*.cpp")
# Documentation doxifile path
set(lib_DOC_DIR "${CMAKE_CURRENT_SOURCE_DIR}/doc/")
link_directories("C:/Program Files/Basler/pylon 5/Development/lib/x64")
set(OpenCV_DIR "C:/OpenCV/3.4.7")
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
set(lib_dep_LIBS PylonC.lib ${OpenCV_LIBS})
add_library(${lib_TARGET} ${lib_SRC})
target_link_libraries(${lib_TARGET} ${lib_dep_LIBS})```
