Find_package from cmake cannot find boost
I referenced this link and made a CMakeLists.txt with the following data:
cmake_minimum_required(VERSION 2.8)
SET(TARGET integrity_scanner)
message("\nBuilding ${TARGET}")
project (${TARGET})
if (UNIX)
message(STATUS "Setting GCC flags")
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g3 -Wall -O0")
else()
message(STATUS "Setting MSVC flags")
#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /EHc-")
endif ()
include_directories ("${PROJECT_SOURCE_DIR}")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
set(BOOST_ROOT C:/boost_1_55_0_dyn)
find_package(Boost 1.55.0 COMPONENTS thread)
SET(SOURCE
IntegrityScanner.cpp
)
SET(HEADERS
IntegrityScanner.h ../BaseApplication.hpp
)
if(Boost_FOUND)
add_definitions(-DDLL_EXPORTS)
add_definitions(-DBOOST_ALL_DYN_LINK)
include_directories("..\\..\\..\\ext_library\\zmq\\zeromq-4.0.3\\include")
include_directories("..\\..\\..\\ext_library\\zmq\\czmq\\czmq-2.1.0\\include")
link_directories("..\\..\\..\\ext_library\\zmq\\zeromq-4.0.3\\lib\\Win32\\Debug")
link_directories("..\\..\\..\\ext_library\\zmq\\czmq\\czmq-2.1.0\\lib\\Win32\\DebugDLL")
include_directories(${Boost_INCLUDE_DIRS})
LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})
add_library(${TARGET} SHARED ${SOURCE} ${HEADERS})
target_link_libraries(${TARGET} ${Boost_LIBRARIES} czmq libzmq)
else()
message(STATUS "Boost_FOUND False")
endif()
Even if I set BOOST_ROOT it fails and gives Boost Found False message . What am I doing wrong here?
Edit: I found that setting Boost_USE_STATIC_LIBS to OFF fixed the problem. But I have to have it ON . What could be wrong here?

I found the reason why this code doesn't work. Since I am giving the ON value for Boost_USE_STATIC_LIBS , the result is that find_package will look for libboost_thread-vc100-mt-1_55 , which it will not find, because building boost will give shared libraries as stated in this link . See Fig. Below:
