# @MACRO: prepend_set()
#
# Utility macro to prepend elements to a variable (reduces boiler-plate code).
#
# Usage::
#
#   prepend_set(<varName> <arg0> <arg1> ...)
#
# Just calls::
#
#   set(<varName> <arg0> <arg1> ... ${<varName>})
#
# NOTE: Prepending is not as efficient as appending so prefer `append_set()`_
# or just ``list(APPEND ...)``.
#
macro(prepend_set VARNAME)
  set(${VARNAME} ${ARGN} ${${VARNAME}})
