| Auto-detection of features like ccache and code coverage |
Ccache is a cache system designed to make compiling faster. When you run Meson for the first time for a given project, it checks if Ccache is installed. If it is, Meson will use it automatically.
If you do not wish to use Ccache for some reason, just specify your
compiler with environment variables CC and/or CXX when first
running Meson (remember that once specified the compiler cannot be
changed). Meson will then use the specified compiler without Ccache.
Coverage
When doing a code coverage build, Meson will check for existence of
the binaries gcovr, lcov and genhtml. If version 3.3 or higher
of the first is found, targets called coverage-text, coverage-xml
and coverage-html are generated. If version 4.2 or higher of the
first is found, targets coverage-text, coverage-xml, coverage-sonarqube
and coverage-html are generated. Alternatively, if the latter two
are found, only the target coverage-html is generated. Coverage
reports can then be produced simply by calling e.g. meson compile coverage-xml. As a convenience, a high-level coverage target is
also generated which will produce all 3 coverage report types, if
possible.
Note that generating any of the coverage reports described above
requires the tests (i.e. meson test) to finish running so the
information about the functions that are called in the tests can be
gathered for the report.
