# vcpkg_apply_patches
|
|
|
|
Apply a set of patches to a source tree. This function is deprecated in favor of the `PATCHES` argument to `vcpkg_from_github()` et al.
|
|
|
|
## Usage
|
|
```cmake
|
|
vcpkg_apply_patches(
|
|
SOURCE_PATH <${SOURCE_PATH}>
|
|
[QUIET]
|
|
PATCHES <patch1.patch>...
|
|
)
|
|
```
|
|
|
|
## Parameters
|
|
### SOURCE_PATH
|
|
The source path in which apply the patches. By convention, this is usually set in the portfile as the variable `SOURCE_PATH`.
|
|
|
|
### PATCHES
|
|
A list of patches that are applied to the source tree.
|
|
|
|
Generally, these take the form of `${CMAKE_CURRENT_LIST_DIR}/some.patch` to select patches in the `port\<port>\` directory.
|
|
|
|
### QUIET
|
|
Disables the warning message upon failure.
|
|
|
|
This should only be used for edge cases, such as patches that are known to fail even on a clean source tree.
|
|
|
|
## Examples

* [libbson](https://github.com/Microsoft/vcpkg/blob/master/ports/libbson/portfile.cmake)
|
|
* [gdal](https://github.com/Microsoft/vcpkg/blob/master/ports/gdal/portfile.cmake)
