## # vcpkg_acquire_msys
##
## Download and prepare an MSYS2 instance.
##
## ## Usage
## ```cmake
## vcpkg_acquire_msys(<MSYS_ROOT_VAR> [PACKAGES <package>...])
## ```
##
## ## 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 automake1.15)`
##
## ## 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)
