Technically, yes. they are the same. But they vary in application of such glissando.

Whereas in Indian music, meend is where the music is actually said to reside (“What happens between the two notes is where the actual music is” – because of the expressiveness with which such meend can be applied), in western music, glissando is mostly used as an articulation to reach the next note. (Only fretless instruments and a few brass instruments use glissando. Piano, the concert flute (and a few other woodwinds), melodic percussion instruments such as glockenspiel and vibraphone don’t use glissando.
