I am trying to compile a Qt project that uses ITK but I am receiving linker errors (see below) from the ITK libraries. I am running on Ubuntu 16.04 and building with Qt 5.9.1. I compiled the ITK version 4.12.1 but I have also tried 4.13 as well as a pre-built version of 4.12.2 from a colleague. I have tried compiling with CMake 3.5 and later with CMake 3.10 but I get the same errors for all of these combinations.
I have generated the list of libraries that I include in my Qt project using the command lorder * | tsort while in the lib folder of the ITK build. This should generate the correct order of include libraries right?
The compiler is complaining about not finding vnl_vector, but I checked the list of linked libraries and -litkvnl as well as -litkvnl_algo are in there and above -lITKCommon which seems to be the problem.
Below I have provided the compile errors as well as the .pri file in which I link to the libraries. Any help would be greatly appreciated!

I would suggest you to convert your project's build system into CMake. I do not advice build ITK with any other system than CMake. Since 2.8.10 it is quite stable, and if you even have a current version, there should be no problems.
Your CMakeLists.txt file would probably look similiar to this:
cmake_minimum_required(VERSION 3.1)
set (CMAKE_CXX_STANDARD 11)
project(HelloWorldItkQt)
# Find includes in corresponding build directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)
# Instruct CMake to run moc and uic automatically when needed.
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
# Find the Qt libraries
find_package(Qt5Gui)
find_package(Qt5Widgets)
find_package(Qt5Core)
#find and enable ITK
find_package(ITK)
include(${ITK_USE_FILE})
# Tell CMake to create the helloworld executable
add_executable(HelloWorldItkQt WIN32 mainwindow.h simpledialog.h mainwindow.cpp simpledialog.cpp main.cpp)
# Use the Widgets module from Qt 5.
target_link_libraries(HelloWorldItkQt Qt5::Widgets Qt5::Gui Qt5::Core ${ITK_LIBRARIES})
