If you need a good code coverage web reporting tool for a github-hosted project, may be your next best friend. I'm already using it on biology and rainbrurpg).

Handling coverage in cmake

You first need to install some package (at least on Debian GNU/Linux) :
sudo apt install gcov lcov gcovr

Then, copy the CodeCoverage.cmake in a cmake/ directory inside your project's repository and add this line to your CMakeLists.txt file:

Generate coverage reports and send them

Now, you need to modify your .travis.yml file and add this :
  # Creating report
  - lcov --version
  - lcov --directory . --capture --output-file
  - lcov --remove '/usr/*' --output-file
  - lcov --list #debug info
  # Uploading report to CodeCov
  - bash <(curl -s || echo "Codecov did not collect coverage reports"
