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