+How to build freeglut with CMake on Windows (MS Visual Studio)
+--------------------------------------------------------------
+1.  Download CMake (http://www.cmake.org/cmake/resources/software.html).
+    Get one of the releases from the binary distribution section.
+2.  Run the CMake installer, install wherever you like. 
+3.  Launch CMake via Start > Program Files > CMake 2.8 > CMake (GUI)
+    (note that the shortcut put by the installer on your desktop does NOT
+    point to the CMake GUI program!)
+4.  In the "Where is the source code" box, type or browse to the root
+    directory of your freeglut source (so that's /freeglut, not
+    /freeglut/src).
+5.  In the "Where to build the binaries" box, type or browse to any
+    folder you like - this will be where the Visual Studio solution will be
+    generated. This folder does not have to exist yet.
+6.  Hit the Configure button near the bottom of the window. 
+7.  Pick your target compiler, make sure that its installed on your
+    system of course!
+8.  Answer Ok when asked if you want to create the build directory. 
+9.  Wait for the configure process to finish. 
+10. The screen will now have some configuration options on it, for
+    instance specifying whether you want to build static and/or shared
+    libraries (see below for a complete list). When you've selected your
+    options, click the Configure button again.
+11. The Generate button at the bottom will now be enabled. Click Generate.
+12. The build files will now be generated in the location you picked. 
+
+You can now navigate to the build directory you specified in step 5.
+Open the freeglut.sln file that was generated in your build directory,
+and compile as usual
+
+
+How to build freeglut on UNIX
+-----------------------------
+- Make sure you have cmake installed. Examples:
+  - Debian/Ubuntu: apt-get install cmake
+  - Fedora: yum install cmake
+  - FreeBSD: cd /usr/ports/devel/cmake && make install
+  Or directly from their website:
+  http://www.cmake.org/cmake/resources/software.html
+- Make sure you have the basics for compiling code, such as C compiler
+  (e.g., GCC) and the make package.
+- Also make sure you have packages installed that provide the relevant
+  header files for x11 (including xrandr) and opengl (e.g.,
+  libgl1-mesa-dev, libx11-dev and libxrandr-dev on Debian/Ubuntu).
+- Install XInput: libxi-dev / libXi-devel
+- Run 'cmake .' in the freeglut directory to generate the makefile.
+- Run 'make' to build, and 'make install' to install freeglut.
+- If you wish to change any build options run 'ccmake .'

+Breakdown of CMake configuration options
+----------------------------------------
+CMAKE_BUILD_TYPE            [Empty, Debug, Release] Can be overriden by
+                            passing it as a make variable during build.
+CMAKE_INSTALL_PREFIX	    Installation prefix (e.g. /usr/local on UNIX)
+FREEGLUT_BUILD_DEMOS	    [ON, OFF] Controls whether the demos are
+                            built or not.
+FREEGLUT_BUILD_SHARED_LIBS  [ON, OFF] Build freeglut as a shared library
+FREEGLUT_BUILD_STATIC_LIBS  [ON, OFF] Build freeglut as a static library
+FREEGLUT_GLES               [ON, OFF] Link with GLEs libraries instead
+                            of OpenGL
+FREEGLUT_PRINT_ERRORS       [ON, OFF] Controls whether errors are
+                            default handled or not when user does not
+                            provide an error callback
+FREEGLUT_PRINT_WARNINGS     [ON, OFF] Controls whether warnings are
+                            default handled or not when user does not
+                            provide an warning callback
+FREEGLUT_REPLACE_GLUT       [ON, OFF] For non-Windows platforms,
+                            freeglut is by default built as -lglut. if
+                            off, built as -lfreeglut. On Windows,
+                            libraries are always built as freeglut.
+INSTALL_PDB                 [ON, OFF] MSVC only: controls whether debug
+                            information files are included with the
+                            install or not
