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