[CMake] LINK_DIRECTORIES visual studio 2010

[Louis Hoefler]

Hello everyone.
I have a simple CMake file

cmake_minimum_required(VERSION 2.8)

IF(DEFINED USEFCGI)
  SET(BACKENDLIB wtfcgi)
ELSE(DEFINED USEFCGI)
  SET(BACKENDLIB wthttp)
ENDIF(DEFINED USEFCGI)

ADD_EXECUTABLE(construction.wt
  construction.cpp
)

if(WIN32)
  INCLUDE_DIRECTORIES(D:/work/boost_1_46_1 D:/work/wt-3.1.10/src 
D:/work/wt-3.1.10/build)
  LINK_DIRECTORIES(D:/work/wt-3.1.10/build/src/Release 
D:/work/wt-3.1.10/build/src/http/Release)
else(WIN32)
  INCLUDE_DIRECTORIES(/usr/include/Wt)
endif(WIN32)

# For FastCGI deployment:
TARGET_LINK_LIBRARIES(construction.wt ${BACKENDLIB} wt)

If I use this file for visual studio 2010 project file generation the 
paths in LINK_DIRECTORIES are not set. What am I doing wrong?

Thank you, Louis
