# Find OpenCV Library
|
||||
# See http://sourceforge.net/projects/opencvlibrary/
|
||||
#----------------------------------------------------------
|
||||
#
|
||||
## 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
|
||||
# - OpenCV 2.0: MinGW, MSVC2008, GCC4
