+ * libncurses - Required, TestDisk and PhotoRec use a text user interface, Ncurses library and development files must be available.
+ * Ext2fs library - Optional, used by TestDisk to list files from ext2/ext3/ext4 partition and by PhotoRec to be able to carve the free space from an ext2/ext3 partition instead of the whole partition
+ * EWF library - Optional, TestDisk and PhotoRec use it to access Expert Witness Compression Format files (ie Encase files)
+ * Iconv - Optional, used to handle unicode filenames
+ * Jpeg library - Optional, used by PhotoRec to improved JPEG recovery rate
+ * NTFS library - Optional, used by TestDisk to list files from NTFS partition
+ * Reiserfs library - Optional, used by TestDisk to list files from reiserfs partition
+ * zlib library - Optional, used by PhotoRec to decompress gzipped content
+ * Qt5 library - Optional, required for QPhotoRec and to update the configure script.
