title: CMake failing to statically link SDL2
body: <p>I'm trying to build a simple SDL2 game with CMake and MSYS Makefiles.</p>
  
  <p>I want to statically link SDL2 so I can distribute a single executable without having to include the SDL2.dll.</p>
  
  <p>Here's my <code>CMakeLists.txt</code> file:</p>
  
  <pre><code>project(racer-sdl)
  
  cmake_minimum_required(VERSION 2.8)
  
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
  set(CMAKE_EXE_LINKER_FLAGS "-static")
  
  include(FindPkgConfig)
  pkg_search_module(SDL2 sdl2)
  if (SDL2_FOUND)
    message(STATUS "Using SDL2")
    add_definitions(-DUSE_SDL2)
    include_directories(${SDL2_INCLUDE_DIRS})
    link_directories(${SDL2_LIBRARY_DIRS})
    link_libraries(${SDL2_LIBRARIES})
  else ()
    message(FATAL_ERROR "Missing SDL2")
  endif ()
  
  file(GLOB SOURCE_FILES src/*.cpp src/*.hpp)
  add_executable(${PROJECT_NAME} ${SOURCE_FILES})
  TARGET_LINK_LIBRARIES(${PROJECT_NAME} ${SDL2_LIBRARIES})
  </code></pre>
  
  <p>I can build fine without the <code>-static</code> linker flag, but with it I get long list of undefined references.</p>
