c++ - Installing OpenCV with GUI on Ubuntu -

-

it seems have messed things up. forgot install dependencies of opencv on ubuntu. specific, want install opencv on ubuntu 14.04 gui support. noticed there package named gtk+-2.0 required opencv. did

sudo apt-get install libgtk2.0-dev

or thing that. installed alright. installed other dependencies specified here.

however, when run cmake according tutorial, says that

gtk+-2.0` not found

so opencv built without gui support. there environmental variable should set before run cmake?

i can detect gtk+-2.0 by

pkg-config --modversion gtk+-2.0`

which outputs 2.24.23. also, remember adding search path gtk+-2.0, thing 

/usr/lib/x86_64-linux-gnu/pkgconfig

is there this?

thanks.
