title: How to add ICU library to project?
body: <p>Help me please. I would like to add ICU library to my project. My cmake version is 2.8.12.2.</p>
  
  <p>There is CMakeLists.txt</p>
  
  <blockquote>
    <p>cmake_minimum_required(VERSION 2.8)</p>
    
    <p>project(test1)</p>
    
    <p>set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}) <br> set(CMAKE_CXX_COMPILER
    /usr/bin/g++) <br>set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}
    -D_GLIBCXX_USE_CXX11_ABI=0 -std=c++11 -Wall")</p>
    
    <p>find_package(Boost 1.54.0 COMPONENTS filesystem system regex
    unit_test_framework REQUIRED) <br>find_package(ICU 52.0 REQUIRED )</p>
    
    <p>include_directories(${Boost_INCLUDE_DIR})
    <br>link_directories(${Boost_LIBRARY_DIR})</p>
    
    <p>add_executable(test1 src/dictionary.cpp 
          src/main.cpp
          ) <br> target_link_libraries( test1 ${Boost_LIBRARIES} pthread
          )</p>

  <p>I have installed ICU libraries: libicu-dev, libicu-dev:i386, libicu52, libicu52:i386, libicu52-dbg:i386</p>
  
  <p>But once I run CMake, I get the following error message:</p>
  
  <pre><code>CMake Error at CMakeLists.txt:10 (find_package):
    By not providing "FindICU.cmake" in CMAKE_MODULE_PATH this project has
    asked CMake to find a package configuration file provided by "ICU", but
    CMake did not find one.
  
    Could not find a package configuration file provided by "ICU" (requested
    version 52.1) with any of the following names:
  
      ICUConfig.cmake
      icu-config.cmake
  
    Add the installation prefix of "ICU" to CMAKE_PREFIX_PATH or set "ICU_DIR"
    to a directory containing one of the above files.  If "ICU" provides a
    separate development package or SDK, be sure it has been installed.
  </code></pre>
  
  <p>What should I do? Help me please.</p>
