Yeah,actually I find libqt5 in usr/lib/ ,but when i try to use command ldd libcaffe.so.1.0.0-rc3 |grep opencv,then i get the following :

but when i open libQT5IopenGL.so, i cant't find reference to qt_5

Never encountered this, but from https://stackoverflow.com/questions/36128645/error-on-execution-version-qt-5-not-found-required-by
I would suggest trying first

sudo apt-get install qt5-default

and if it still not working, force point your execution by prepending LD_LIBRARY_PATH as such

Issue happens because you have Qt installed in /usr/lib/x86_64-linux-gnu from distro which ld will use by default. To avoid such issues you can compile with -rpath or run with LD_LIBRARY_PATH=/path/to/your/Qt/libs/location to help linker find needed Qt version.

eg. LD_LIBRARY_PATH=/path/to/your/Qt/libs/location make -j<nthreads> ...

or fiddle a bit in the makefiles to point it to the correct qt lib paths

Good luck!

Thank you very much for your kindness, I will try your method later.
