Helpers.h fails to build without std:: namespace

[chuckleplant]

https://github.com/kylemcdonald/ofxCv/blob/b316c6314ba5b7dc29b5c0e1718124362e9fb024/libs/ofxCv/include/ofxCv/Helpers.h#L139

I'm on windows, visual studio 2015. This line may be missing std::vector?

I'm not tracking this repo just using source, hope this helps if it's an actual issue. These are the changes I had to make to fix my build:

i think this should be fixed now.
