short-description: Auto-detection of features like ccache and code coverage |

# Feature autodetection |
|
|
|
Meson is designed for high productivity. It tries to do as many things |
|
automatically as it possibly can. |
|
|
|
Ccache |
|
-- |
|
|
|
[Ccache](https://ccache.dev/) 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 can not 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. 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. `ninja |
|
coverage-xml`. As a convenience, a high-level *coverage* target is |
|
also generated which will produce all 3 coverage report types, if |
|
possible.
