#[===[.md:
# 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)
