Gabriel B. Nunes	88e54ca1c0	Work around CMake bug that mangles install dir CMake has a long-standing bug/feature (see [here](https://cmake.org/pipermail/cmake/2015-March/060204.html) and reply [here](https://cmake.org/pipermail/cmake/2015-March/060209.html)) which can mangle certain path variables by attempting to make them into relative paths if you try to set them with CACHE PATH. Say you have your OpenCV download at `/path/on/my/computer/to/opencv/`. What actually happens is that if you try to set this variable by invoking CMAKE with `-DCMAKE_INSTALL_PREFIX=/my/desired/install/path`, what you end up is not `/usr/local/` and not `my/desired/install/path`, but instead, this monstrosity: `/path/on/my/computer/to/opencv/src/OpenCV-build//my/desired/install/path`. That is, CMake attempts, for some reason, to turn the path that you passed into a path relative to `${CMAKE_BINARY_DIR}`. See the links I posted above: this is a known (and apparently unfixable) issue with CMake. In OpenCV's case, among other potential issues, this leads to broken paths in `opencv_tests_config.hpp`, which can break the build or cause bizarre behaviour. The fix for this issue, as stated in my links above, is to test that the variable hasn't been set yet with an `if(NOT DEFINED ...)` before attempting to set it. This is what I've implemented here. I admit I don't know enough about OpenCV's internals to know whether you really need to force the install to be in `/usr/local`, but as it stands right now you get neither a clean `/usr/local` path nor a customized `/my/desired/install/path`, but a broken mess. This change at least allows the user to customize their install directory. In the meantime, there's a workaround for this, by explicitly defining the variable as a path with `-DCMAKE_INSTALL_PREFIX:PATH=my/desired/install/path`. But if this change can save anyone else the hours of headaches that I had today, I'll be happy.	8 years ago

cclauss	a347569350	Merge pull request #8150 from cclauss/patch-1 cv2.findContours() no longer modifies source image (#8150) * cv2.findContours() no longer modifies source image Since OpenCV 3.2, cv2.findContours() no longer modifies the source image but returns a modified image as the first of three return parameters. ??? Do I have that correct ??? Also fixed up the code blocks to be valid markdown. * ```python --> @code{.py} Enables syntax highlighting in docs.	8 years ago
