Updated the build config files to deal with the version status. I didn't make the status part of the version variables here, because letters don't play too well with version comparison algorithms (especially with CMake's, which only supports numbers). 2013-09-12 20:37:30 +08:00			`set(OpenCV_VERSION @OPENCV_VERSION_PLAIN@)`
Started top-level CMakeLists.txt file reorganization: cmake scripts are moved to separate folder; refactored BUILD_, INSTALL_, ENABLE_, USE_, WITH_* options. 2012-01-03 21:48:12 +08:00			`set(PACKAGE_VERSION ${OpenCV_VERSION})`

Properly check for version in find_package If I ask for version 2, the current trunk version (version 3), will say it is compatible, which is erroneous. Do not consider different major versions compatible in cmake config file 2015-12-07 07:10:39 +08:00			`if(PACKAGE_FIND_VERSION_MAJOR EQUAL @OPENCV_VERSION_MAJOR@`
