Linking error after making cmake - linker

Question

I have a linker problem under linux. This is my cmake file:
cmake_minimum_required(VERSION 2.6)
# Locate GTest
find_package(GTest REQUIRED Boost)
include_directories(${GTEST_INCLUDE_DIRS})
file(GLOB info_model
"../src/info_model/*.h"
"../src/info_model/*.cpp"
"../src/gcc_xml_parsing/*.h"
"../src/gcc_xml_parsing/*.cpp"
"../src/messages_filed_with_values/*.h"
"../src/messages_filed_with_values/*.cpp"
)
# Link runTests with what we want to test and the GTest and pthread library
add_library(info_model_lib STATIC ${info_model} )
add_executable(runTests_xml unit/gcc_xml_parsing/ut_XMLFile.cpp )
add_executable(runTests_hexDumpUtil unit/info_model/ut_HexDumpUtil.cpp )
add_executable(runTests_cstruct unit/info_model/ut_CStruct.cpp )
add_executable(runTests_primitive_type_field unit/info_model/ut_PrimitiveTypeField.cpp )
add_executable(runTests_enumField unit/info_model/ut_EnumField.cpp )
add_executable(runTests_ArrayOfFields unit/info_model/ut_ArrayType.cpp )
target_link_libraries(runTests_xml ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} pthread boost_regex boost_thread info_model_lib)
target_link_libraries(runTests_hexDumpUtil ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} pthread boost_regex boost_thread info_model_lib)
target_link_libraries(runTests_cstruct ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} pthread boost_regex boost_thread info_model_lib)
target_link_libraries(runTests_primitive_type_field ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} pthread boost_regex boost_thread info_model_lib)
target_link_libraries(runTests_enumField ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} pthread boost_regex boost_thread info_model_lib)
target_link_libraries(runTests_ArrayOfFields ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} pthread boost_regex boost_thread info_model_lib)
However, the linker throwns an error, which start (I didn't provide the whole log, because it is 5 times larger than the below):
libinfo_model_lib.a(XMLFile.cpp.o): In function `bool boost::regex_search<__gnu_cxx::__normal_iterator<char const*, std::string>, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::string> > >, char, boost::regex_traits<char, boost::cpp_regex_traits<char> > >(__gnu_cxx::__normal_iterator<char const*, std::string>, __gnu_cxx::__normal_iterator<char const*, std::string>, boost::match_results<__gnu_cxx::__normal_iterator<char const*, std::string>, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::string> > > >&, boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags, __gnu_cxx::__normal_iterator<char const*, std::string>)':
Thank you for helping

You have to link yours library before boost::regex
target_link_libraries(runTests_xml ${GTEST_LIBRARIES} ${GTEST_MAIN_LIBRARIES} info_model_lib pthread boost_regex boost_thread )
