discordia@0 21 # Instructions:
discordia@0 22 # This cmake file assumes that your source files are laid in out in the
discordia@0 23 # following manner:
discordia@0 24 #
discordia@0 25 # project_dir\ Top level directory of the project.
discordia@0 26 # |---include\ Header files are here.
discordia@0 27 # |---src\ Source files are here.
discordia@0 28 # |---build\ Binaries/objects go here. Run cmake from here.
discordia@0 29 # !---cmake\
discordia@0 30 # | |---modules\ Custom cmake include files, if any, go here.
discordia@0 31 # |---CMakeLists.txt This file.
discordia@0 32 #
discordia@0 33 # You may have more directories, of course, but these are assumed. You probably
discordia@0 34 # want more than one build directory. I normally have build-linux\
discordia@0 35 # and build-windows\ directories.
discordia@0 36 #
discordia@0 37 # Set the App_Name variable, below, to the name of your application and you
discordia@0 38 # are ready to start. Run ccmake, or cmake-gui from within your build
discordia@0 39 # directory, choose the options you need, such as enabling SDL, and you
discordia@0 40 # should be good to go.
discordia@0 41 #
discordia@0 42 # You can uncomment the "SET (CMAKE_VERBOSE_MAKEFILE ON) command if you
discordia@0 43 # need to debug the actual makefile that is generated.
discordia@0 44 #
discordia@0 45 # On windows, you may need to set the SDLDIR environment variable to the location
discordia@0 46 # of your SDL installation before you run cmake-gui.
discordia@0 47 #
discordia@0 48 # When writing path names on Windows, such as when manually specifiying a
discordia@0 49 # file or directory name, either use unix-style forward slashes '/' in the
discordia@0 50 # path names or use double backslashes. If you use a single backslash as the
discordia@0 51 # path name seperator, then cmake will interpret it as an esacpe sequence.
discordia@0 52 # Thus, write "C:/source" or "C:\\source" instead of "C:\source". It's
discordia@0 53 # probably best to use forward slashes in case to ever have a situation
discordia@0 54 # where cmake needs to do recursive processing: each level of cmake will
discordia@0 55 # strip out one of the slashes, so if there are two lev3els of cmake you
discordia@0 56 # need to write \\\, three levels requires \\\\, etc.
discordia@0 57 #
discordia@0 58 # Note that some of the cmake support scripts that find libraries for you
discordia@0 59 # can be controlled by environment variables. For example, you can set the
discordia@0 60 # SDLDIR environment variable before running cmake in order to point to
discordia@0 61 # a different version of SDL than your systems default copy. This is useful
discordia@0 62 # for trying out cutting edge versions of libraries without installing them
discordia@0 63 # system wide.
