have you read the text files( in the downloaded source code) called "README" and "INSTALL" ,and read the install instructions on the web site ?
Then did you install all the required
one of those , from the error, is installing qt and qmake
also you are aware that 2.0
is from 2006 and has NOT!!! been updated in 8 years
it is going to be a bit difficult to build and install on mint 16
a operating system 1.5 GENERATIONS of software newer
now there is a version one year newer 2.2
with a Ubuntu download
--- might never run on mint 16 it is 7 years old after all .
what is it you want to use this program for ?
i am betting there are video editing software already in the Mint 16 software repos
