# Purpose of this CMake script is to support printing of properties fetched
# using a generator expression.
#
# Depending on the generator in use, Ninja, Makefile, other, it is not possible
# to always ensure proper new line on all platforms when calling echo.
# The print.cmake handles this issue by taking a CMake list and prints each item
# in the list on a new line.
#
# This script can be invoked as: `cmake -DLIST="itemA;itemB;..." -P print.cmake`

foreach(item ${LIST})
  execute_process(COMMAND ${CMAKE_COMMAND} -E echo ${item})
