How to add ICU libraries to Android project?

Question

I'm working on Flutter plugin that depends on ICU package. Currently I'm stuck with linking ICU libraries to my project using cmake. Though I've tried to pass an actual path to icu4c dir in different ways, cmake is persistently referring to those parts of ICU package that are bundled with my current Android NDK.

My CMakeLists.txt is the following:

cmake_minimum_required(VERSION 3.10)
cmake_policy(SET CMP0074 NEW)

project(uuid_library VERSION 0.0.1 LANGUAGES C)

add_library(uuid SHARED
"uuid.c"
)

set_target_properties(uuid PROPERTIES
OUTPUT_NAME "uuid"
)

set(CMAKE_PREFIX_PATH "/usr/local/opt/icu4c")
set(ICU_ROOT "/usr/local/opt/icu4c")
set(ICU_DEBUG ON)

message(STATUS "CMAKE_PREFIX_PATH: ${CMAKE_PREFIX_PATH}")
message(STATUS "ICU_ROOT: ${ICU_ROOT}")

find_package(ICU COMPONENTS i18n uc)

message(STATUS "ICU_FOUND: ${ICU_FOUND}")
message(STATUS "ICU_INCLUDE_DIRS: ${ICU_INCLUDE_DIRS}")
message(STATUS "ICU_LIBRARIES: ${ICU_LIBRARIES}")

if (ICU_FOUND)
  include_directories(${ICU_INCLUDE_DIRS})
  target_link_libraries(uuid PRIVATE ICU::i18n ICU::uc)
else()
  message(FATAL_ERROR "ICU libraries not found")
endif()

target_compile_definitions(uuid PUBLIC DART_SHARED_LIB)

if (ANDROID)
  # Support Android 15 16k page size.
  target_link_options(uuid PRIVATE "-Wl,-z,max-page-size=16384")
endif()

Now I get the following error while trying to build example project depending on my plugin:

Launching lib/main.dart on sdk gphone x86 64 in debug mode...

FAILURE: Build failed with an exception.

As you can see from the FindICU's debug output, though both CMAKE_PREFIX_PATH and ICU_ROOT are actually set to a proper value /usr/local/opt/icu4c, ICU_INCLUDE_DIR still refers to the include dir inside the NDK toolchain. How can I force find_package() or find_library() functions to link the right ICU package?
