# Feature autodetection |
|
|
|
Meson is designed for high productivity. It tries to do as many things automatically as it possibly can. |
|
|
|
CCache |
|
-- |
|
|
|
[CCache](https://ccache.samba.org/) 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 the existence of binaries `gcovr`, `lcov` and `genhtml`. If the first one is found, it will create targets called *coverage-text* and *coverage-xml*. If the latter two or a new enough `gcovr` is found, it generates the target *coverage-html*. You can then generate coverage reports just by calling e.g. `ninja coverage-xml`.
