SOLVED: Built target jsonserver Makefile:137" recipe for target 'all' failed

Hi there I am trying to compile hyperion. Up to cmake everything goes well, but make is not able to finish correctly.
i run:
cmake -DENABLE_DISPMANX=OFF -DENABLE_SPIDEV=OFF -DENABLE_X11=ON -DCMAKE_BUILD_TYPE=Release -Wno-dev ..
then:
make -j $(nproc)

it ends up with error:
v4l2-grabber /x11 compilation error - see image.

Any idea what could be wrong?
g++ is version 4.9.2-10

OK, so I found a solution.

$ sudo apt-get install apt-file
$ sudo apt-file update
$ apt-file search "X11/extensions/XShm.h"

and then I installed missing module libxext-dev and then compilation run successfully.

CAN BE MARKED AS SOLVED.
