Can't Build VisualStudio Project with CMAKE

[Dan Rinkes]

When trying to build a Visual Studio project, CMAKE returns an error like this.

C:\dev\libfreespace-build>cmake -G "Visual Studio 10" ..\libfreespace
-- WinDDK in
CMake Error at CMakeLists.txt:170 (message):
  Could not locate hid.lib

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
WINDDK_INCLUDE_DIR (ADVANCED)
   used as include directory in directory C:/dev/libfreespace

-- Configuring incomplete, errors occurred!

Some notes taken while investigating. These refer to the file FindWinDDK.cmake.

The line below is part of the problem. On, Windows, the “IS_DIRECTORY” function fails if the directory is actually a symbolic link. So, if you have a symbolic link from C:\WinDDK, WINDDK_DIR is not going to get set here.
       IF(NOT DEFINED WINDDK_DIR AND EXISTS "C:/WinDDK" AND IS_DIRECTORY "C:/WinDDK")
              FILE(GLOB WINDDK_DIR "C:/WinDDK/7*")
       ENDIF()

Also, even when the above does pass, I think it’s a problem. There are two directories that will match this, C:\WinDDK\7600.16385.0 and C:\WinDDK\7600.16385.1. WINDDK_DIR gets set to “C:/WinDDK/7600.16385.0;C:/WinDDK/7600.16385.1” Then, it uses this value to try to resolve WINDDK_INCLUDE_SEARCH_DIRS and eventually WINDDK_INCLUDE_DIR.

       # Search for header files
       SET(WINDDK_INCLUDE_SEARCH_DIRS ${WINDDK_DIR}/inc )
       FIND_PATH(WINDDK_INCLUDE_DIR api/hidpi.h
              PATHS ${WINDDK_INCLUDE_SEARCH_DIRS} )
       SET(WINDDK_INCLUDE_DIR ${WINDDK_INCLUDE_DIR}
              CACHE STRING "Directory containing Ms WinDDK header files")

 At some point, after the list of DDK directories is created, it needs to somehow choose one revision to use.
