[Regex] Undefined symbols when using Boost::regex_icu from CMake

Dear Boost::regex_icu users!

I've ran into a problem while using the regex library of Boost with ICU compatibility mode.
I am getting a lot of linker errors about ICU functions. This is all the linker errors I get: https://pastebin.com/eCj8Pi2m
I am pretty sure that I'm getting this while using `boost::u32regex_token_iterator`.

I'm using CMake to build my project and CPM (A wrapper around FetchContent).

Here is my CMakeLists.txt:

```
cmake_minimum_required(VERSION 3.12)
project(termeszetes_nyelvi)

include(cmake/CPM.cmake)

set(CMAKE_CXX_STANDARD 26)
set(BOOST_REGEX_STANDALONE ON)

set(ICU_ROOT "C:/Program Files/icu")

CPMAddPackage("gh:boostorg/regex#boost-1.89.0")

add_executable(termeszetes_nyelvi main.cpp
regex_utils/regex_match_collector.hpp
regex_utils/split_string_using_regex.hpp
print_utils/format_map.hpp)
target_link_libraries(termeszetes_nyelvi PRIVATE Boost::regex_icu)```

I have tried linking to all ICU components, but it did not resolve my errors.

This is the function template that causes the error: https://gist.github.com/nevemlaci/3a1a14516626b263f11e887f9433cfd4

Please tell me if you need any more details.

Thank you in advance,

Laci
