 * [`librpm`](http://rpm.org/): Slower fallback for rpm package count. Needed on openSUSE.
 * [`libplist`](https://github.com/libimobiledevice/libplist): Binary `plist` file parser ( macOS ). Needed for iTerm2 Terminal font and WM Theme.
 * [`libcJSON`](https://github.com/DaveGamble/cJSON): Needed for Windows Terminal font ( WSL ).
+* [`freetype`](https://www.freetype.org/): Needed for Termux font detection ( Android ).
