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.
|
|
-#
|
|
-#
|
|
-# tested with:
|
|
-# - OpenCV 2.1: MinGW, MSVC2008
|
