How can I compile a project in two different ways in Travis CI?
I have a project written using Qt that supports both Qt4 and Qt5.
I currently have a travis configured to compile a project using gcc and clang for linux and OSX.
I would like to split it up again so that the project builds both Qt4 and Qt5 as separate assemblies, as well as 8 different permutations in a common split across OS, compiler and Qt version.
My current travis.yml
language: cpp
os:
- linux
- osx
compiler:
- gcc
- clang
script: mkdir build && cd build && cmake .. -DWITH_SERVER=1 && make
install: ./travis-dependencies.sh
cache: apt
Choosing Qt4 vs Qt5 is configurable using additional cmake options.
How can I change this to split my assembly matrix?

The Travis support team recommendation is to use environment variables to split the build:
language: cpp
env:
- QT="-DWITH_QT4=0"
- QT="-DWITH_QT4=1"
os:
- linux
- osx
compiler:
- gcc
- clang
script: mkdir build && cd build && cmake .. $QT -DWITH_SERVER=1 && make
install: ./travis-dependencies.sh
cache: apt
