CI for Qt app: build with different Qt versions - c++

Question

I use Travis-CI for continuous integration for my simple Qt app. My .travis.yml file looks like this (based on this gist):
language: cpp
before_install:
- sudo add-apt-repository --yes ppa:ubuntu-sdk-team/ppa
- sudo apt-get update -qq
- sudo apt-get install -qq g++ qt4-qmake libqt4-dev qt5-qmake qtbase5-dev
script:
- qmake -qt=qt4 -v
- qmake -qt=qt4
- make
- make -k check
- make clean
- qmake -qt=qt5 -v
- qmake -qt=qt5
- make
- make -k check
This configuration allows me to build my app (and run tests) with default Qt libraries in Ubuntu (Qt 4.8.1 and Qt 5.0.2).
Is there any way to build app with other Qt versions (4.7.x, 4.8.x, 5.1.x and so on)?

With this .travis.yml you will get 10 separate build jobs - number of elements in matrix section. Each build job will install specified Qt version and use it for app building in Ubuntu with Qt 4.8 - 5.7 and OS X with Qt 5.5 and 5.7 (or latest version).
If you want to build your app for Windows, you can try AppVeyor CI service. Example config (Qt 5.3 - 5.7):
version: '{build}'
init:
- git config --global core.autocrlf input
environment:
matrix:
- QT5: C:\Qt\5.3\mingw482_32
MINGW: C:\Qt\Tools\mingw482_32
- QT5: C:\Qt\5.4\mingw491_32
MINGW: C:\Qt\Tools\mingw491_32
- QT5: C:\Qt\5.5\mingw492_32
MINGW: C:\Qt\Tools\mingw492_32
- QT5: C:\Qt\5.6\mingw49_32
MINGW: C:\Qt\Tools\mingw492_32
- QT5: C:\Qt\5.7\mingw53_32
MINGW: C:\Qt\Tools\mingw530_32
matrix:
fast_finish: true
before_build:
- set PATH=%MINGW%\bin;%QT5%\bin;%PATH%
build_script:
- qmake -v
- qmake -r
- mingw32-make
I use these configs in my project - qtcsv. See it for updates and build logs.

You can find more version of Qt by adding this beineri's ppa.
For example, version 5.4 can be added:
before_install:
- sudo add-apt-repository ppa:beineri/opt-qt541 -y
install:
- sudo apt-get install qt54base qt54websockets
script:
- source /opt/qt54/bin/qt54-env.sh
