The echo command of the host system may have slight variations between shell built-in echo and the echo command provided by the OS. Especially the Windows OS echo command is different from practical any other echo command. This means that the currently used `COMMAND echo -e "<text>"` does not work universally. This commit introduces `etc/cmake/print.cmake` which allow to print a CMake list where each item is printed on a new line, to get the desired behavior on the `print-ot-config` target. Using `cmake -E echo <text>` ensures identical behaviour across different systems. Signed-off-by: Torsten Rasmussen <[email protected]>

# 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`
