Confusions about opencv version about orb_slam2 HOT 5 OPEN

@maxb91 I passed this issue by uninstall opencv 3 , ROS should have installed opencv 2.

from orb_slam2.

What's the output when u issue this command?
$ pkg-config --modversion opencv

Mine is opencv 2.4.8, and I have no problem in compiling orb_slam2

from orb_slam2.

Even I have the same error.
$ pkg-config --modversion opencv
3.1.0 is the output
Is it needed to move to lower version of opencv? Is there any recommended way to overcome this problem?

Hi, I am trying to compile ORB_SLAM2 on OSX 10.11.12 with ROS Indigo. i have opencv 3.1 installed (built form source) under /usr/local/lib and /usr/local/include (directories searched by default), and also opencv 2.4.12 under /usr/local/Cellar(installed through brew package manager), which I can link to, in case opencv 3.1 is not compatible.
How can I provide the path to the usr/local/Cellar opencv(2.4.12) instead of the default /usr/local/lib opencv(3.1), in the sense that what variables/flags do i provide in the cmake file/with the cmake command on the terminal, to make it find opencv 2.4 under Cellar?
I tried some experiments with "CPPFLAGS" but it didn't seem to work.
I still got the error:

CMake Error at CMakeLists.txt:31 (find_package):
Could not find a configuration file for package "OpenCV" that is compatible
with requested version "2.4.3".

The following configuration files were considered but not accepted:

/usr/local/share/OpenCV/OpenCVConfig.cmake, version: 3.1.0

Thanks!

Hi, I've just installed OpenCV from scratch and I've got the same problem when running build.sh. Have you already found a solution to this issue?
