# WinCE support now relies on the presence of platform files, found in cmake/modules/platform
# Cmake 2.8.0 doesn't include WinCE platform files by default, but working ones can be found
# on CMake's bugtracker :
# http://public.kitware.com/Bug/view.php?id=7919
#
# for cmake 2.8.0 get the following patch only :
# http://public.kitware.com/Bug/file_download.php?file_id=2944&type=bug
#
# after applying the patch, you can enable the WinCE build by specifying :
# cmake [...] -DCMAKE_SYSTEM_NAME=WinCE -DCMAKE_SYSTEM_VERSION=X.XX
# (where X.XX is your actual WinCE version, e.g. 5.02 for Windows Mobile 6)
#
# Note that you should have a proper cross-compilation environment set up prior to running
# cmake, ie. the PATH, INCLUDE and LIB env vars pointing to your CE SDK/toolchain.
