Are you sure yout Qt4.5 has the mysql plugin built in? There's only two
cases for the plugins (AFAIK):
a) real plugins as shared objects in the plugins dir
b) built directly into the static Qt libs
So obviously in case a) you don't need to link against the mysql-plugin,
because Qt will load it itself during runtime and in the second case it
should be part of the QtSql library.
Can you show the relevant cpp file and cmake code?
