MP3 Diags finds problems in MP3 files and helps the user fix many of them. It looks at both the audio part (VBR info, quality, normalization) and the tags containing track information (ID3). It has a tag editor, which can download album information (including cover art) from MusicBrainz and Discogs, as well as paste data from the clipboard. Track information can also be extracted from a file's name. Another component is the file renamer, which can rename files based on the fields in their ID3V2 tag (artist, track number, album, genre, etc.).

In most cases it's easier to use pre-built binaries, which are available for Windows and for several major Linux distributions from the main download page: http://mp3diags.sourceforge.net/unstable/010_getting_the_program.html
Build instructions for Windows are at: http://mp3diags.sourceforge.net/unstable/010_getting_the_program.html#sourceWindows
Build instructions for Linux / others are at: http://mp3diags.sourceforge.net/unstable/010_getting_the_program.html#sourceGeneric
Basically, you should run BuildMp3Diags.hta on Windows and Install.sh elsewhere.
Note that even if there is a CMakeLists.txt, CMake isn't officially supported. If it works for you – fine. If it doesn't – you're on your own.
