    1.24 +# Instructions:
    1.25 +# This cmake file assumes that your source files are laid in out in the 
    1.26 +# following manner:
    1.27 +#
    1.28 +#   project_dir\		Top level directory of the project.
    1.29 +#     |---include\		Header files are here.
    1.30 +#     |---src\			Source files are here.
    1.31 +#     |---build\		Binaries/objects go here.  Run cmake from here.
    1.32 +#     !---cmake\
    1.33 +#     |     |---modules\        Custom cmake include files, if any, go here.
    1.34 +#     |---CMakeLists.txt	This file.
    1.35 +#
    1.36 +# You may have more directories, of course, but these are assumed.  You probably
    1.37 +# want more than one build directory.  I normally have build-linux\ 
    1.38 +# and build-windows\ directories.
    1.39 +#
    1.40 +# Set the App_Name variable, below, to the name of your application and you
    1.41 +# are ready to start.  Run ccmake, or cmake-gui from within your build
    1.42 +# directory, choose the options you need, such as enabling SDL, and you 
    1.43 +# should be good to go.
    1.44 +#
    1.45 +# You can uncomment the "SET (CMAKE_VERBOSE_MAKEFILE ON) command if you
    1.46 +# need to debug the actual makefile that is generated.
    1.47 +#
    1.48 +# On windows, you may need to set the SDLDIR environment variable to the location
    1.49 +# of your SDL installation before you run cmake-gui.
    1.50 +#
    1.51 +# When writing path names on Windows, such as when manually specifiying a 
    1.52 +# file or directory name, either use unix-style forward slashes '/' in the
    1.53 +# path names or use double backslashes. If you use a single backslash as the
    1.54 +# path name seperator, then cmake will interpret  it as an esacpe sequence.
    1.55 +# Thus, write "C:/source" or "C:\\source" instead of "C:\source".  It's
    1.56 +# probably best to use forward slashes in case to ever have a situation
    1.57 +# where cmake needs to do recursive processing: each level of cmake will
    1.58 +# strip out one of the slashes, so if there are two lev3els of cmake you
    1.59 +# need to write \\\, three levels requires \\\\, etc.
    1.60 +#
    1.61 +# Note that some of the cmake support scripts that find libraries for you
    1.62 +# can be controlled by environment variables.  For example, you can set the
    1.63 +# SDLDIR environment variable before running cmake in order to point to
    1.64 +# a different version of SDL than your systems default copy. This is useful
    1.65 +# for trying out cutting edge versions of libraries without installing them
    1.66 +# system wide.
