## # vcpkg_apply_patches
|
|
##
|
|
## Apply a set of patches to a source tree.
|
|
##
|
|
## ## 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
|
|
##
|
|
## * [boost](https://github.com/Microsoft/vcpkg/blob/master/ports/boost/portfile.cmake)
|
|
## * [freetype](https://github.com/Microsoft/vcpkg/blob/master/ports/freetype/portfile.cmake)
|
|
## * [libpng](https://github.com/Microsoft/vcpkg/blob/master/ports/libpng/portfile.cmake)
