CMake not linking static library - c++

Question

I have a static library (openexr.lib) that was compiled in debug mode. I'm trying to link this library to a project I've created using CMake. Here's my folder structure.
+-- myproject
| +-- Demo
| +-- build
| +-- libraries
| +-- openexr.lib
| +-- cmake
| +-- GenerateVS2015.bat
| +-- CMakeLists.txt
| +-- Demo.cpp
| +-- stdafx.cpp
So, you can see that I have the openexr.lib located in the libraries directory. I have verified that this .lib file has been compiled as a static library and the file size is approximately 64mb. Then, I have a batch file which is found in the cmake directory which tries to build the projects. Here's what my batch script looks like.
#echo off
set startingDir=%CD%
set basepath=%~dp0
set builddir=%basepath%\..\build
if exist %builddir% (#RD /S /Q %builddir%)
mkdir %builddir%
cd %builddir%
cmake -G "Visual Studio 14 2015 Win64" .. %*
cd %startingDir%
So, this basically creates the build directory if it doesn't already exist (otherwise it clears it so it can repopulate everything). Then, it calls the cmake command with the visual studio generator option.
Now, here's what's in my CMakeLists.txt file:
CMAKE_MINIMUM_REQUIRED (VERSION 2.8)
PROJECT (MyProject)
IF ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "MSVC")
ADD_DEFINITIONS(-DBUILD_DLL)
SET(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} xmllite.lib")
string(REGEX REPLACE "/bin/[^/]*$" "" VCINSTALLDIR "${CMAKE_C_COMPILER}")
message(STATUS "Guessed MSVC directory: ${VCINSTALLDIR}")
ENDIF()
ADD_LIBRARY(openexr STATIC IMPORTED GLOBAL)
SET_TARGET_PROPERTIES(openexr PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/libraries/openexr.lib)
ADD_EXECUTABLE(MyDemo ${CMAKE_CURRENT_SOURCE_DIR}/Demo.cpp ${CMAKE_CURRENT_SOURCE_DIR}/stdafx.cpp)
TARGET_LINK_LIBRARIES(MyDemo openexr)
When I run my batch file, it generates the MyDemo.vcxproj file correctly. I can see it's setup to compile with the target extension .exe (which is what I want). But, when I try to build the project, I get the following error message:
C:\myproject\build\Debug\MyDemo.exe : fatal error LNK1120: 78 unresolved externals
If I open up the property pages for my demo project, I can see that under the Linker section that is trying to link to my openexr.lib file.
But, for some reason it continues to fail every time I try to build the executable file. Can anyone provide a reason why?
