How do I deploy in-tree qt library to Raspberry Pi?

sly110

All,
I have a library that I have build for the raspberry pi 3 using Qt5.8. It is built in-tree as a sub project. What is the best method to deploy this to rpi so that my main rpi qt app can use it. I have been manually copying it to lib directory.
This is the pro setup:


QT       += network
QT       += serialport

QT       -= gui

TARGET = rpi-utils
TEMPLATE = lib

DEFINES += RPIUTILS_LIBRARY

SOURCES += rpiutils.cpp \
           PIgpio.cpp \
           IOserial.cpp

HEADERS += rpiutils.h\
        rpi-utils_global.h \
        PIgpio.h \
        IOserial.h \
        acs_hfo_comm_intf.h

unix {
    target.path = /usr/lib
    INSTALLS += target
}

Thank you for any help.

Thank you ambershark!
I will use that method and mark as solved.

I usually have a lib directory in my application distribution tar/gz. I would put my supporting libs there.

I have bash scripts that build my tar/gz distribution. Also in that script I have a start script which sets the LD_LIBRARY_PATH so it can use the local lib directory rather than one at a system level.

@sly110 No problem, if you'd like some examples of my set up let me know and I can post one here.
