Compiling C++ project with CMake and FrontPanel

I’m trying to compile my project using CMake. okFrontPanelDLL.h and okFrontPanel.dll are in the root folder of the project as is CMakeLists.txt. Has anyone used CMake with FrontPanel? What am I doing wrong in CMake?

When I compile I see the following errors:

CMakeFiles\TestAcquireStore.dir/objects.a(NeuralInterfaces.cpp.obj): In function `OpalKellyLegacy::okCFrontPanel::okCFrontPanel()':
C:/Users/nated/Google Drive/College/bci/AcquireStore/okFrontPanelDLL.h:1208: undefined reference to `__imp_okFrontPanel_Construct'
CMakeFiles\TestAcquireStore.dir/objects.a(NeuralInterfaces.cpp.obj): In function `OpalKellyLegacy::okCFrontPanel::~okCFrontPanel()':
C:/Users/nated/Google Drive/College/bci/AcquireStore/okFrontPanelDLL.h:1210: undefined reference to `__imp_okFrontPanel_Destruct'

Here’s my CMakeLists.txt

cmake_minimum_required(VERSION 3.6)
project(AcquireStore CXX)

#use C++14
set(CMAKE_CXX_STANDARD 14)
#output build results in the root directory
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR})

#pick some files
set(SOURCE_FILES
        NeuralInterfaces.h
        NeuralInterfaces.cpp
        NeuralInterface.hpp
        Tests.cpp
)

#use FrontPanel
find_path(FrontPanel_INCLUDE_DIR okFrontPanelDLL.h)
find_library(okFrontPanel_LIBRARY okFrontPanel)

#add frontpanel to source libraries
if(FrontPanel_INCLUDE_DIR AND okFrontPanel_LIBRARY)

    set(okFrontPanel_FOUND TRUE)

    include_directories(${Front_Panel_INCLUDE_DIR})

    set(SOURCE_LIBRARIES
            ${okFrontPanel_LIBRARY}
    )
endif()

#compile and link the library
if(okFrontPanelFOUND EQUAL TRUE)
    #create the dll
    add_library(AcquireStore SHARED ${SOURCE_FILES})
    set_target_properties(AcquireStore PROPERTIES LINKER_LANGUAGE CXX)

    target_link_libraries(AcquireStore ${SOURCE_LIBRARIES})
endif()

#we need to create an executable or CMake won't work
add_executable(TestAcquireStore ${SOURCE_FILES})
