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