## # 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)
