Changing of qbs.installDir has no effect after build.

Group
{
fileTagsFilter: "application"
qbs.install: true
qbs.installDir: 'whatever'
}

Build project. Deploy it. Change qbs.installDir to something else. Try deploy it again. It will be deployed on the same place as it was before. Reparsing Qbs wont help. I dont have any idea how to force it and where the old install path stuck.
