libicuuc.so.52, needed libboost_regex-mt.so - c++

Question

Introduction
I want to a compile a code that uses ICU and libboost. For this purpose I am using the following install.sh file. The problem is that I am getting this error:
/usr/bin/ld: warning: libicuuc.so.52, needed by /opt/boost-1.54.0/lib/libboost_regex.so, not found (try using -rpath or -rpath-link)
I know that I have to add something in the cmakeLists.txt file:
set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS} -rpath=/opt/icu_52.1/")
But It's not working:
c++: error: unrecognized command line option ‘-rpath=/opt/icu_52.1/’
When I try: set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS} -Wl,-rpath=/opt/icu_52.1/")
error: /usr/bin/ld: warning: libicuuc.so.52, needed by /opt/boost-1.54.0/lib/libboost_regex-mt.so, not found (try using -rpath or -rpath-link)

Add to your CMakeLists.txt file:
link_directories(/opt/icu_52.1/lib)
You can also try to see if somebody has written a find package for ICU, anyway it's not among the standard cmake modules.
