I got `unresolved external symbol` while using `ExternalProject_Add`, how should I solve this?

Here is my CMakeLists.txt:

ExternalProject_Add(
  subhook
  GIT_REPOSITORY https://github.com/Zeex/subhook.git
  GIT_TAG v0.8.2
  SOURCE_DIR        "${CMAKE_CURRENT_BINARY_DIR}/subhook-src"
  BINARY_DIR        "${CMAKE_CURRENT_BINARY_DIR}/subhook-build"
  CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=${EXTERNAL_INSTALL_LOCATION} -DSUBHOOK_STATIC=ON -DSUBHOOK_TESTS=OFF SUBHOOK_FORCE_32BIT=ON)

include_directories(${EXTERNAL_INSTALL_LOCATION}/include)
link_directories(${EXTERNAL_INSTALL_LOCATION}/lib)

add_executable(t_test ${_testfile})
add_dependencies(t_test subhook)

I will get this error

t_test.obj : error LNK2019: unresolved external symbol __imp__subhook_new referenced in function ...

I cannot directory add

target_link_libraries(t_test subhook)

which may show this error:

CMake Error at test/base/CMakeLists.txt:24 (target_link_libraries):
  Target "subhook" of type UTILITY may not be linked into another target.
  One may link only to INTERFACE, OBJECT, STATIC or SHARED libraries, or to
  executables with the ENABLE_EXPORTS property set.

I’m on windows.
How can I fix this one?
Thanks everyone for reading.

Maybe the superfluous parentheses after the include string?

Hi Volker, I fixed the typo but I still got the same error.
