I already played around with sfml and cmake on a ubuntu systems. I was supprised by the fact, that the original cmake on windows did not come with a sfml script.
So I ended up here...
...still there was no support for windows. So I add support for visual studo 2008.
You just have to set the the enviroment variable SFMLDIR to the SFML directory.
And make sure to have a SET(CMAKE_BUILD_TYPE Release) in your cmake project!!!
Because the vs compiler uses the debug option by default. You would end up with the release SFML components in a debug executable. That can cause unexpected behavior and crashes of you application!
I do not have that much experienc with cmake so this file is still limited to create release versions only. Maybe I add support for the debug files later.
I created working nmake files and vs2008 projects with this:
Save this file as "FindSFML.cmake"
# Locate SFML library
# This module defines
# SFML_LIBRARY, the name of the library to link against
# SFML_FOUND, if false, do not try to link to SFML
# SFML_INCLUDE_DIR, where to find SFML headers
#
# Created by Nils Hasenbanck. Based on the FindSDL_*.cmake modules,
# created by Eric Wing, which were influenced by the FindSDL.cmake
# module, but with modifications to recognize OS X frameworks and
# additional Unix paths (FreeBSD, etc).

# 2010-04-04 Add support for wxWIN with visual studio 2008 (9.0)

And before you all copy FindSFML.cmake in your cmake module directory here is a much more elegant way:
Create a directory like "cmake_modules" in you project directory and move the "FindSFML.cmake" there.
Then add the line set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules") to your "CMakeLists.txt".
Now you can use it with the regular Find_Package(SFML REQUIRED COMPONENTS System).
This is very useful because people that compile your project dont have to copy around the "FindSFML.cmake" script.
EDIT: I added the SFML_main lib so you dont get linking errors if you create windows GUI applications (the one without the cmd promt)
