# core/subprojects ## What's this? What _is_ this? - These are subprojects accessible to the `core` meson project. ## icu - When building for Linux, [ICU](https://icu.unicode.org) must already be installed. The system ICU will be used instead of the subproject. - Patches for icu (i.e. meson build files) are in [`packagefiles/icu`](./packagefiles/icu/) - It would be preferable to use meson's [wrapdb](https://mesonbuild.com/Wrapdb-projects.html), and in fact the patchfiles here are sourced from that project. - However, having our own patchfiles allows for slimming down ICU, at least until the wrapdb version is more configurable [mesonbuild/wrapdb#950](https://github.com/mesonbuild/wrapdb/issues/950)
