Building 0.5.1 from source / errors within libakaze.so related to OpenCV

[KBentley57]

All,

I'm building 0.5.1 from source, with a few other packages from source. Everything has compiled fine, but when I go to run opensfm to try the berlin example, I get the following error:

bentleykw@centos:~/src/SupportPackages/build$ opensfm

ImportError: /home/bentleykw/src/SupportPackages/build/opensfm/src/opensfm/opensfm/src/third_party/akaze/libakaze.so: undefined symbol: _ZTVN2cv11_InputArrayE

Any advice? C++filt translates that symbol to vtable for cv::_InputArray, but ldd shows everything linked correctly to the opencv libs. I'm more of a c++ expert than python, so I'm not really sure what's causing the error.

Any advice? Using gcc 9, opencv 4.5.2, and python 3.9.

Thanks!
