具有Boost和CMake的单线程应用程序

我正在编写一个单线程应用程序。我使用CMake进行编译。我的应用程序是使用Boost使用C ++编写的。当运行'make'时，我的应用程序链接失败，并显示以下错误消息：

Linking CXX executable whisk
cd <project>/build/src && /usr/bin/cmake -E cmake_link_script CMakeFiles/whisk.dir/link.txt --verbose=1
/usr/bin/c++      CMakeFiles/whisk.dir/driver_simdag.cpp.o CMakeFiles/whisk.dir/whisk.cpp.o CMakeFiles/whisk.dir/driver_miror.cpp.o CMakeFiles/whisk.dir/driver.cpp.o CMakeFiles/whisk.dir/main.cpp.o  -o whisk -rdynamic -lboost_program_options

//lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

这是错误本身：

 undefined reference to symbol 'pthread_rwlock_unlock@@GLIBC_2.2.5'

我在src目录中的CMakeLists.txt文件如下：

file(GLOB whisk_SRC "[a-zA-Z]*.cpp")
add_executable(whisk ${whisk_SRC})

FIND_PACKAGE( Boost 1.40 COMPONENTS program_options log REQUIRED )
set(Boost_USE_MULTITHREADED      OFF)
# set_property(TARGET whisk PROPERTY Boost_USE_MULTITHREADED OFF)
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )

set_property(TARGET whisk PROPERTY CXX_STANDARD 11)
set_property(TARGET whisk PROPERTY CXX_STANDARD_REQUIRED ON)

target_link_libraries(whisk ${Boost_PROGRAM_OPTIONS_LIBRARY})

install(TARGETS whisk DESTINATION bin)

我如何告诉CMake和Boost我根本不使用pthreads，并且我希望编译单线程版本？
