QMake make install problems

[Comer352l]

What do you mean when you talk about a separate "installation point" ? I tried the following

QMFILES = file1.qm file2.qm file3.qm
target.path = /opt/myapp
tstarget.path = /opt/myapp
tstarget.files = $$QMFILES
INSTALLS += target tstarget

QMFILES = file1.qm file2.qm file3.qm
target.path = /opt/myapp
tstarget.path = /opt/myapp
tstarget.files = $$QMFILES
INSTALLS += target tstarget

but it doesn't work .
