Setting the correct INSTALLS value for installing a static library

[bobbaluba]

I'm building a non-qt library using qmake, and I want to be able to run the following commands to install the library:

@qmake ../mylib
make
make install@

I've done this before for applications, using the target and installs variable, like this:

@target.path = /usr/bin
INSTALLS += target@

But this doesn't seem to work for libraries. What's the recommended way to do this?

EDIT:

I tried this, but it didn't work

@DESTDIR = ../lib

#TODO: this doesn't work! Find a way to copy binaries to /usr/libs folder
libraryfiles.path = /usr/lib/
libraryfiles.files += $$DESTDIR/mylib.a
INSTALLS += libraryfiles@
