[ITK] cross-compiling ITK function to Windows

[Matt McCormick]

Hi Andre,

When configuring the build for the ThresholdImage executable, make
sure to set the ITK_DIR CMake configuration variable to the
appropriate ITK build tree directory.  For example,

  cmake . -DCMAKE_TOOLCHAIN_FILE=./Toolchain-mingw32.cmake
-DCMAKE_INSTALL_PREFIX=/home/X/mingw-install -G "Unix Makefiles"
-DITK_DIR=/home/X/ITK-build

Hope this helps,
Matt
