Why does openvas give an error when installing?

Question

ubuntu

Ubuntu 20.04, I put the vulnerability scanner, when installing openvas-smb, it gives an error:

[ 93%] Linking C executable winexe
/usr/bin/ld: cannot find -lunistring
/usr/bin/ld: cannot find -lunistring
collect2: error: ld returned 1 exit status
make[2]: *** [winexe/CMakeFiles/winexe.dir/build.make:140: winexe/winexe] Error 1
make[1]: *** [CMakeFiles/Makefile2:194: winexe/CMakeFiles/winexe.dir/all] Error 2
make: *** [Makefile:152: all] Error 2

I install like this:

cd openvas-smb &&\
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH &&\
mkdir build &&\
cd build/ &&\
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm .. &&\
make &&\
make install &&\
cd /opt/gvm/src

installation fails at make step
