[CMake] problems in building opencv (zlib.h: No such file or directory)

[Jean-Christophe Fillion-Robin]

Hi Saverio,

Make sure you install zlib dev package. That way the header will be found
on the system.

On Ubuntu 14.04, you could do it using the following command:

$ sudo apt-get install zlib1g-dev

See http://packages.ubuntu.com/trusty/zlib1g-dev
