3 # A generalized cmake file for developing cross-platform games.
4 #
5 # (c) 2010 Sarah Eris Horsley Caffee
7 # Instructions:
8 # This cmake file assumes that your source files are laid in out in the
9 # following manner:
10 #
11 # project_dir\ Top level directory of the project.
12 # |---include\ Header files are here.
13 # |---src\ Source files are here.
14 # |---build\ Binaries/objects go here. Run cmake from here.
15 # !---cmake\
16 # | |---modules\ Custom cmake include files, if any, go here.
17 # |---CMakeLists.txt This file.
18 #
19 # You may have more directories, of course, but these are assumed. You probably
20 # want more than one build directory. I normally have build-linux\
21 # and build-windows\ directories.
22 #
23 # Set the App_Name variable, below, to the name of your application and you
24 # are ready to start. Run cmake, ccmake, or cmake-gui from within your build
25 # directory, choose the options you need, such as enabling SDL or OGRE,
26 # and you should be good to go.
27 #
28 # You can uncomment the "SET (CMAKE_VERBOSE_MAKEFILE ON) command if you
29 # need to debug the actual makefile that is generated.
30 #
31 # On windows, you may need to modify some of the variables farther down in
32 # this file so that cmake knows where SDL or other support libraries
33 # and their header files can be found on the system.
34 #
35 # When writing path names on Windows, such as when manually specifiying a
36 # file or directory name, either use unix-style forward slashes '/' in the
37 # path names or use double backslashes. If you use a single backslash as the
38 # path name seperator, then cmake will interpret it as an esacpe sequence.
39 # Thus, write "C:/source" or "C:\\source" instead of "C:\source". It's
40 # probably best to use forward slashes in case to ever have a situation
41 # where cmake needs to do recursive processing: each level of cmake will
42 # strip out one of the slashes, so if there are two lev3els of cmake you
43 # need to write \\\, three levels requires \\\\, etc.
44 #
45 #
46 # Note that some of the cmake support scripts that find libraries for you
47 # can be controlled by environment variables. For example, you can set the
48 # SDLDIR environment variable before running cmake in order to point to
49 # a different version of SDL than your systems default copy. This is useful
50 # for trying out cutting edge versions of libraries without installing them
51 # system wide.
55 # Probably not needed, but it may save someone else a headache someday.
