TeXstudio rpm install: QT dependencies (e.g. libQtGui.so.4)

I'm trying to install TeXstudio on a Scientific Linux 7.2 machine with an rpm. My problem is, that I'm missing the following dependencies: `# rpm -ivh texstudio-qt4-2.10.8-6.1.x86_64.rpm warning: texstudio-qt4-2.10.8-6.1.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID ea279317: NOKEY error: Failed dependencies: libQtGui.so.4()(64bit) is needed by texstudio-qt4-2.10.8-6.1.x86_64 libQtSvg.so.4()(64bit) is needed by texstudio-qt4-2.10.8-6.1.x86_64 libpoppler-qt4.so.4()(64bit) is needed by texstudio-qt4-2.10.8-6.1.x86_64 ` I tried looking for the packages with e.g. yum provides "*/libQtGui.so.4()" which results in e.g. qt-x11-4.8.5-11.el7.i686, but after I installed it the same dependency was still missing. Does anyone have an idea? Thanks a lot!
