RedHat Enterprise Linux 8 (CentOS 8) does not provide the needed libraries (in particular not the Qt4 libs). Everything needed can be installed using the Fedora 29 packages:
dnf install https://extras.getpagespeed.com/redhat/8/noarch/RPMS/getpagespeed-extras-release-8-6.el8.gps.noarch.rpm
dnf install qt-x11 mesa-libGLU
and answering "y" to all questions (attention - this installs a non-default repository). Alternatively, the Fedora 29 packages can be installed:
  wget https://archives.fedoraproject.org/pub/archive/fedora/linux/releases/29/Everything/x86_64/os/Packages/q/qt-4.8.7-41.fc29.x86_64.rpm

wget https://archives.fedoraproject.org/pub/archive/fedora/linux/releases/29/Everything/x86_64/os/Packages/q/qt-settings-29.0-1.fc29.noarch.rpm
In addition, the qt-settings RPM may have to be installed. It is available from EPEL, or also from Fedora 29.
  dnf install mesa-libGLU qt-4.8.7-41.fc29.x86_64.rpm qt-common-4.8.7-41.fc29.noarch.rpm qt-x11-4.8.7-41.fc29.x86_64.rpm qt-settings-29.0-1.fc29.noarch.rpm
 
The qt-settings RPM is also available from EPEL. Alternatively, a non-default repository can be installed:
dnf install https://extras.getpagespeed.com/redhat/8/noarch/RPMS/getpagespeed-extras-release-8-6.el8.gps.noarch.rpm
dnf install mesa-libGLU qt-x11
and answering "y" to all questions. However, using the FC29 packages is recommended.
