Error while assembling bitcoin v0.15.0

[progof]

Hello,

I'm collecting a clone of bitcoin and an error appeared on the make process, tell me how to fix it:

^{make[2]: *** No rule to make target `qt/res/icons/clone_splash.png', needed by `qt/qrc_bitcoin.cpp'.  Stop.
make[2]: Leaving directory `/root/clone/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/clone/src'
make: *** [all-recursive] Error 1}

^{make[2]: *** No rule to make target `qt/res/icons/clone_splash.png', needed by `qt/qrc_bitcoin.cpp'.  Stop.}

Please check whether the file (clone_splash.png) does exist (spelling error?) and whether you are executing the command in the correct directory.

Thanks for the hint, this bug is fixed. And the following error occurred:

You seem to be missing a few files. 
Did you check whether the needed files (correct names) are inside the correct directory ?

Did you follow the build process written on github ?
