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 these files you add a special parameter when configuring the source tree: cmake -DCMAKE_TOOLCHAIN_FILE= . For example, to use the Debian GNU/Linux MinGW package, run CMake like this: cmake -DCMAKE_TOOLCHAIN_FILE=CMake/i586-mingw32msvc.cmake .
