vcpkg/scripts/cmake/vcpkg_acquire_msys.cmake

## # vcpkg_acquire_msys
##
## Download and prepare an MSYS2 instance.
##
## ## Usage
## ```cmake
## vcpkg_acquire_msys(<MSYS_ROOT_VAR>
##     PACKAGES <package>...
##     [NO_DEFAULT_PACKAGES]
##     [DIRECT_PACKAGES <URL> <SHA512> <URL> <SHA512> ...]
## )
## ```
##
## ## Parameters
## ### MSYS_ROOT_VAR
## An out-variable that will be set to the path to MSYS2.
##
## ### PACKAGES
## A list of packages to acquire in msys.
##
## To ensure a package is available: `vcpkg_acquire_msys(MSYS_ROOT PACKAGES make automake1.16)`
##
## ### NO_DEFAULT_PACKAGES
## Exclude the normal base packages.
##
## The list of base packages includes: bash, coreutils, sed, grep, gawk, diffutils, make, and pkg-config
##
## ### DIRECT_PACKAGES
## A list of URL/SHA512 pairs to acquire in msys.
##
## This parameter can be used by a port to privately extend the list of msys packages to be acquired.
## The URLs can be found on the msys2 website[1] and should be a direct archive link:
##
##     https://repo.msys2.org/mingw/i686/mingw-w64-i686-gettext-0.19.8.1-9-any.pkg.tar.zst
##
## [1] https://packages.msys2.org/search
##
## ## Notes
## A call to `vcpkg_acquire_msys` will usually be followed by a call to `bash.exe`:
## ```cmake
## vcpkg_acquire_msys(MSYS_ROOT)
## set(BASH ${MSYS_ROOT}/usr/bin/bash.exe)
##
## vcpkg_execute_required_process(
##     COMMAND ${BASH} --noprofile --norc "${CMAKE_CURRENT_LIST_DIR}\\build.sh"
##     WORKING_DIRECTORY ${CURRENT_BUILDTREES_DIR}/${TARGET_TRIPLET}-rel
##     LOGNAME build-${TARGET_TRIPLET}-rel
## )
## ```
##
## ## Examples
##
## * [ffmpeg](https://github.com/Microsoft/vcpkg/blob/master/ports/ffmpeg/portfile.cmake)
## * [icu](https://github.com/Microsoft/vcpkg/blob/master/ports/icu/portfile.cmake)
## * [libvpx](https://github.com/Microsoft/vcpkg/blob/master/ports/libvpx/portfile.cmake)
