This folder contains a collection of toolchains definition in order to
support cross compilation. The naming scheme is the following:
This directory contains a collection of toolchain definitions for cross
compilation, currently limited to compiling Win32 binaries on Linux.
The toolchain file naming scheme is as follows:
host-system-compiler.cmake
to use this at the time you run the initial cmake command use the
following parameter
-DCMAKE_TOOLCHAIN_FILE=./toolchains/XXX-XXX-XXX.cmake
which maps to file in this folder.
To use these files you add a special parameter when configuring the source tree:
cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
For example, to use the Debian GNU/Linux MinGW package, run CMake like this:
cmake -DCMAKE_TOOLCHAIN_FILE=CMake/linux-i586-mingw32msvc.cmake .
For more details see this article:

Introduction
------------
The GLFW documentation is written in LaTeX. Besides being powerful, LaTeX is
also very attractive since all the necessary tools for dealing with LaTeX
documentation are both free and ported to a wide variety of platforms. Another
advantage is that the LaTeX files are written in plain text, which means that
version control systems such as CVS handle them perfectly without having to
treat the documents as binary files.
The documents
-------------
There are two main documents:
glfwrm.tex - The GLFW Reference Manual
glfwug.tex - The GLFW Users Guide
In addition, there is a common LaTeX style file that sets up things
such as page formatting and useful macros:
glfwdoc.sty - Common GLFW document styles and macros
Requirements
------------
Of course you need LaTeX installed on your system in order to compile the GLFW
documentation. If you are using a Unix-like operating system, then your
package system most likely has a version of LaTeX adapted for your system. If
not, the easiest way to get a full LaTeX system is to download/get the TeXLive
CD from http://www.tug.org/texlive/. It has all the necessary software for
Windows, Mac OS X and most popular Unix-like operating systems.
A number of LaTeX packages have to be installed in order to compile the
GLFW documentation successfully:
color
fancyhdr
hyperref
lastpage
listings
needspace
textcase
times
titling
These packages are all available on the TeXLive CD. Just make sure that
you have checked all these packages when installing TeXLive, or get them
in some other way if you do not have the TeXLive CD.
