[Qgis-developer] how to run coverage tests ?

[Sandro Santilli]

Travis found a problem i n master while running the coverage test:
https://travis-ci.org/qgis/QGIS/jobs/109576392#L1468

but my attempt to run the test locally failed:

 [strk at cdb:/usr/src/qgis/build/master] ctest -R coverage
 Test project /usr/src/qgis/build/master
 No tests were found!!!

I rebuilt making sure ENABLE_COVERAGE was set, but I get the
same exact result. What am I missing ?

It would be useful if the cmake call could end with a summary
of what's enabled and what not, and ideally with WARNINGs
when ENABLE_TESTS was set but not all tests were really enabled.
