## # vcpkg_execute_required_process
##
## Execute a process with logging and fail the build if the command fails.
##
## ## Usage
## ```cmake
## vcpkg_execute_required_process(
## COMMAND <${PERL}> [<arguments>...]
## WORKING_DIRECTORY <${CURRENT_BUILDTREES_DIR}/${TARGET_TRIPLET}-dbg>
## LOGNAME <build-${TARGET_TRIPLET}-dbg>
## )
## ```
## ## Parameters
## ### ALLOW_IN_DOWNLOAD_MODE
## Allows the command to execute in Download Mode.
## [See execute_process() override](../../scripts/cmake/execute_process.cmake).
##
## ### COMMAND
## The command to be executed, along with its arguments.
##
## ### WORKING_DIRECTORY
## The directory to execute the command in.
##
## ### LOGNAME
## The prefix to use for the log files.
##
## This should be a unique name for different triplets so that the logs don't conflict when building multiple at once.
##
## ## Examples
##
## * [ffmpeg](https://github.com/Microsoft/vcpkg/blob/master/ports/ffmpeg/portfile.cmake)
## * [openssl](https://github.com/Microsoft/vcpkg/blob/master/ports/openssl/portfile.cmake)
## * [boost](https://github.com/Microsoft/vcpkg/blob/master/ports/boost/portfile.cmake)
## * [qt5](https://github.com/Microsoft/vcpkg/blob/master/ports/qt5/portfile.cmake)
