* [scripts-audit] vcpkg_acquire_msys (#17687) * [vcpkg.cmake] Change find_package function -> macro in order to shorten trace (#17997) switch from function to macro * [scripts-audit] z_vcpkg_apply_patches (#18013) * [scripts-audit] z_vcpkg_escape_regex_control_characters (#18013) * [scripts-audit] vcpkg_fail_port_install (#18054) Note that this change allows existing failures; it changes MATCHES to STREQUAL, meaning that vcpkg_fail_port_install(ON_ARCH "arm") now succeeds on arm64; this change in behavior is fine (IMO) since it strictly succeeds when it used to fail.

# z_vcpkg_apply_patches
|
|
|
|
**Only for internal use in vcpkg helpers. Behavior and arguments will change without notice.**
|
|
|
|
Apply a set of patches to a source tree.
|
|
|
|
```cmake
|
|
z_vcpkg_apply_patches(
|
|
SOURCE_PATH <path-to-source>
|
|
[QUIET]
|
|
PATCHES <patch>...
|
|
)
|
|
```
|
|
|
|
The `<path-to-source>` should be set to `${SOURCE_PATH}` by convention,
|
|
and is the path to apply the patches in.
|
|
|
|
`z_vcpkg_apply_patches` will take the list of `<patch>`es,
|
|
which are by default relative to the port directory,
|
|
and apply them in order using `git apply`.
|
|
Generally, these `<patch>`es take the form of `some.patch`
|
|
to select patches in the port directory.
|
|
One may also download patches and use `${VCPKG_DOWNLOADS}/path/to/some.patch`.
|
|
|
|
If `QUIET` is not passed, it is a fatal error for a patch to fail to apply;
|
|
otherwise, if `QUIET` is passed, no message is printed.
|
|
This should only be used for edge cases, such as patches that are known to fail even on a clean source tree.
