How to export target's properties when installing targets in CMake

I have the following sample project which I would like to export PROTOCOLS_LIST properties.

cmake_minimum_required(VERSION 3.14.0)
project(exported_props LANGUAGES CXX)

add_library(protocols ...)
set_target_properties(protocols PROPERTIES PROTOCOLS_LIST "IP" "TCP" "UDP")

install(TARGETS protocols EXPORT protocol)
install(EXPORT protocol DESTINATION ${CMAKE_BINARY_DIR})

When installing the above sample code, the created protocol.cmake file will not contain my custom property PROTOCOLS_LIST.

Is it possible to pass some target's properties when installing TARGETS?

By default, CMake installs only specific set of target's properties.

For tell CMake to install additional properties you could list that properties in the EXPORT_PROPERTIES target's property:

# Tell CMake to install PROTOCOLS_LIST property for the target.
set_property(TARGET protocols APPEND PROPERTY EXPORT_PROPERTIES PROTOCOLS_LIST)
