<LANG>_COMPILER_LAUNCHER does not use the passed list

Usage
1

I would need a compiler launcher and arguments passed to it.
https://cmake.org/cmake/help/latest/prop_tgt/LANG_COMPILER_LAUNCHER.html states that you can pass a semicolon-separated list. Nevertheless if I do, I only get the first element in double quotes. The other arguments are dropped.
Am I just miss-reading the documentation? Or using it wrong?

Minimal reproducer

cmake_minimum_required(VERSION 3.30)
project(Example CXX)

add_executable(example cmake_example.cpp)
set(launcher /path/to/my/launcher -bla)
set_target_properties(example PROPERTIES CXX_COMPILER_LAUNCHER ${launcher})

Don’t use set_target_properties() for properties which take more than one value; the command interprets its arguments as alternating property value property value… You’d need to quote the value, but I’d say it’s safer to just use set_property():

set_property(TARGET example PROPERTY CXX_COMPILER_LAUNCHER ${launcher})

Thanks. It was not clear to me that the property-value pair in https://cmake.org/cmake/help/latest/command/set_target_properties.html can not contain lists as value.
