## # vcpkg_execute_build_process
##
## Execute a required build process
##
## ## Usage
## ```cmake
## vcpkg_execute_build_process(
## COMMAND <cmd> [<args>...]
## [NO_PARALLEL_COMMAND <cmd> [<args>...]]
## WORKING_DIRECTORY </path/to/dir>
## LOGNAME <log_name>)
## )
## ```
## ## Parameters
## ### COMMAND
## The command to be executed, along with its arguments.
##
## ### NO_PARALLEL_COMMAND
## Optional parameter which specifies a non-parallel command to attempt if a
## failure potentially due to parallelism is detected.
##
## ### 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
##
## * [icu](https://github.com/Microsoft/vcpkg/blob/master/ports/icu/portfile.cmake)
