The goal of this project is to have a clean Travis CI build, with specs:

Build system: qmake
C++ compiler: gcc
C++ version: C++11
Libraries: STL only
Code coverage: none
Source: one single file, main.cpp

More complex builds:

Use C++14: travis_qmake_gcc_cpp14
Use C++17: travis_qmake_gcc_cpp17
Use C++20: travis_qmake_gcc_cpp20
Add Bio++: travis_qmake_gcc_cpp11_bpp
Add Boost: travis_qmake_gcc_cpp11_boost
Add Boost.Test: travis_qmake_gcc_cpp11_boost_test
Add Coverity Scan: travis_qmake_gcc_cpp11_coverity
Add code coverage: travis_qmake_gcc_cpp11_gcov
Add Doxygen: travis_qmake_gcc_cpp11_doxygen
Add gprof: travis_qmake_gcc_cpp11_gprof
Add OCLint: travis_qmake_gcc_cpp11_oclint
Add Qt: travis_qmake_gcc_cpp11_qt
Add SFML: travis_qmake_gcc_cpp11_sfml
Add Rcpp: travis_qmake_gcc_cpp11_rcpp
Add Urho3D: travis_qmake_gcc_cpp11_urho3d
Add Wt: travis_qmake_gcc_cpp11_wt

Less complex builds:
