[CMake] Cannot find "modules" directory on MacOS

[Chris Wolf]

Today is my first time messing with CMake, so I don't have any prior
versions.

Well, I was reading this page:

http://www.cmake.org/Wiki/CMake:How_To_Write_Platform_Checks

because I wanted to use:

INCLUDE (CheckIncludeFiles)

This page has the following paragraph:

    Additionally to the builtin commands, cmake offers more commands implemented 
    by cmake script files, called modules. These files are located in the cmake 
    module directory, on UNIX systems is this by default /usr/local/share/CMake/Modules . 

So before I even just tried the module, I went looking for it to see what 
the source looked like.  When I didn't find it in /usr/share/cmake-2.8 
or /usr/local/share/cmake-2.8, as suggested by the Wiki page and this
thread:

http://www.mail-archive.com/cmake@cmake.org/msg04790.html

I just assumed something was wrong and that the installation was not complete.

In fact, I jumped to a conclusion - apparently, when those extra resources
are in the application bundle, then can be found, in-place, even with the command-line
cmake executable.  In other words, I was wrong - those files are fine to 
be under, "/Applications/CMake\ 2.8-2.app/Contents/"

Thanks for quickly pointing that out.  I have more development experience
on UNIX/Linux, which is how I made this mistake.  However, I would recommend
updating that Wiki page to mention that on MacOS the modules are 
located within the application bundle, under
"/Applications/CMake 2.8-2.app/Contents/share/cmake-2.8/Modules"

Also, I think the man pages still need to be copied, or symlinked,
or the MANPATH updated.

Thanks,

Chris Wolf
