 ### Linux/Fedora
 
+**On Fedora < 34**:
 On Fedora, you can install all the needed third-party dependencies by using the built-in `dnf` package manager:
 
 ```bash
 dnf install --assumeyes make automake gcc gcc-c++ cmake git qt5  boost mercurial xerces-c-devel unzip freeglut-devel wget eigen3-devel
 ```
 
+**On Fedora >= 34**:
+
+```
+dnf install --assumeyes make automake gcc gcc-c++ cmake git qt5-qtbase-devel boost mercurial xerces-c-devel unzip freeglut-devel wget eigen3-devel giflib-devel libjpeg-devel sqlite-devel
+```

 ### Centos7
 
 Packages shipped with Centos7, or installed by the YUM package manager, unfortunately are often too old. So, one needs to circumvent that, either by using pre-compiled bundles, or building from sources.
