我开始here但是已经发生了很大变化我认为最好开始一个新问题，特别是因为我认为该问题中的CMake问题已经解决了。
背景
我正在尝试设置一个项目的基本shell，它涉及将C ++ midtier连接到Oracle 12c数据库。
环境
1. MinGW-64（x86_64-4.9.1-release-win32-sjlj-rt_v3-rev2）
2. Windows 7 64位
3. CLion 2016.1.1（所以我使用的是CMake 3.5.1）
4.所有OCCI DLL都在system32中
5. lib和dll都在C:/Users/hurst/libs
的CMakeLists.txt
cmake_minimum_required(VERSION 3.4)
project(Oracle)
#set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
set(CMAKE_PREFIX_PATH C:/Users/hurst/libs)
find_library(OCCI1 oraociei12)
find_library(OCCI2 oci)
find_library(OCCI3 orannzsbb12)
find_library(OCCI4 oraocci12)
set(SOURCE_FILES
src/main.cpp
include/occi.h)
add_executable(Oracle ${SOURCE_FILES})
target_link_libraries(Oracle ${OCCI1} ${OCCI2} ${OCCI3} ${OCCI4})
代码
#include <occi.h>
using namespace oracle::occi;
int main()
{
Environment *env = Environment::createEnvironment();
Environment::terminateEnvironment(env);
}
错误

有什么建议吗？感谢。

修改
基于我在another SO answer上所做的一些阅读，我打破了target_link_libraries（）调用，这样每次调用就是一个库：
target_link_libraries（Oracle $ {OCCI1}）
target_link_libraries（Oracle $ {OCCI2}）
target_link_libraries（Oracle $ {OCCI3}）
target_link_libraries（Oracle $ {OCCI4}）
然后我尝试通过向上/向下移动$ {OCCI2}来运行它，看看它是否成功（即1234,2134,1324,1342），因为$ {OCCI2}是OCI lib，代表了基本的C API， Oracle界面。它不起作用，同样的错误。
