链接时报错cannot find -lDolphinDB

Question

在win10上用minGW编译dolphindb c++插件，CMakeList.txt如下

cmake_minimum_required(VERSION 3.0)
project(PluginMQTTClient)

set(CMAKE_CXX_STANDARD 11)
include_directories("${CMAKE_CURRENT_SOURCE_DIR}/../include")
include_directories("${CMAKE_CURRENT_SOURCE_DIR}/lib/")

aux_source_directory(${CMAKE_CURRENT_SOURCE_DIR}/src/ PluginSrc)
aux_source_directory(${CMAKE_CURRENT_SOURCE_DIR}/lib/ MQTTSrc)

set(CMAKE_VERBOSE_MAKEFILE ON)
if (WIN32 OR MINGW)
    set (platform_macro "-DWINDOWS")
elseif (UNIX)
    set (platform_macro "-DLINUX")
    add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)
endif ()
message("platform: ${platform_macro}")


set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall ${platform_macro} ")
#add_compile_options( "-std=c++0x"  "-fPIC" )
#add_compile_options("-std=c++11" "-fPIC" ${platform_macro} "-Wall")

add_library(${PROJECT_NAME} SHARED ${PluginSrc} ${MQTTSrc} ./src/templates/posix_sockets.c)

link_directories("${CMAKE_BINARY_DIR}")
link_directories("D:/DolphinDB/DolphinDB_Win64_V1.00.23/server")
set(CMAKE_EXE_LINKER_FLAGS "-Wl,-rpath,.")
if (WIN32)
    target_link_libraries(${PROJECT_NAME}  pthread WS2_32 DolphinDB)
elseif (UNIX)
    target_link_libraries(${PROJECT_NAME} pthread)
endif ()

编译后出错：
