+Subject: [PATCH] cmake: Fix build with OpenCV
+
+The FindOpenCV module assumes that OpenCV in installed into a separate
+directory which makes sense for cluster machines etc.
+
+However, on Gentoo OpenCV is installed by portage and the corresponding Cmake
+module can be used directly.

+-## 1: Setup:
+-# The following variables are optionally searched for defaults
+-#  OpenCV_DIR:            Base directory of OpenCv tree to use.
+-#
+-## 2: Variable
+-# The following are set after configuration is done: 
+-#  
+-#  OpenCV_FOUND
+-#  OpenCV_LIBS
+-#  OpenCV_INCLUDE_DIR
+-#  OpenCV_VERSION (OpenCV_VERSION_MAJOR, OpenCV_VERSION_MINOR, OpenCV_VERSION_PATCH)
+-#
+-#
+-# Deprecated variable are used to maintain backward compatibility with
+-# the script of Jan Woetzel (2006/09): www.mip.informatik.uni-kiel.de/~jw
+-#  OpenCV_INCLUDE_DIRS
+-#  OpenCV_LIBRARIES
+-#  OpenCV_LINK_DIRECTORIES

+-## 3: Version

+-# 2010/04/07 Benoit Rat, Correct a bug when OpenCVConfig.cmake is not found.
+-# 2010/03/24 Benoit Rat, Add compatibility for when OpenCVConfig.cmake is not found.
+-# 2010/03/22 Benoit Rat, Creation of the script.
+-#
+-#
