win7下使用mingw编译VTK
1.安装Qt和CMake工具
2.添加mingw所在的exe文件路径（D:\Qt\Qt5.6.0\Tools\mingw492_32\bin）
到系统环境变量PATH
3.解压VTK-7.1.1.zip到F:\VTK-7.1\VTK-src下
4.新建F:\VTK-7.1\VTK-bin
//5、6步骤不加也可以
5.修改VTK-src下CMakeLists.txt文件中set(VTK_USE_WIN32_THREADS 1)为set(VTK_USE_PTHREADS 1)
6.在VTK-src/ThirdParty/libxml2/vtklibxml2/threads.c中#include “libxml.h”后添加：
#undef HAVE_WIN32_THREADS
7.启动CMake，指定source code路径为VTK-src路径，build the binaries路径为VTK-bin路径
8.点击Configure，编译器默认为use default nativecompilers，选择mingw makefiles，点击finish
9.选中grouped和advanced复选框
10.改变CMake->CMAKE_BUILD_TYPE为release
11.改变CMAKE->CMAKE_INSTALL_PREFIX为F:\VTK-7.1\releaselib（生成最后头文件和库的路径）
12.改变Module中Module_vtkGUISupportQt、Module_vtkGUISupportQtOpenGL、
Module_vtkGUISupportQtSQL、Module_vtkGUISupportQtWebkit、
Module_vtkRenderingQt、Module_vtkViewsQt的状态为选中
13.改变VTK中VTK_Group_Qt的状态为选中
//14、15不添加也可以
14.点击Add Entry，添加name为QT_QMAKE_EXECUTABLE，type为PATH，
value为D:\Qt\Qt5.6.0\5.6\mingw49_32\bin\qmake.exe
15.点击Add Entry，添加name为CMAKE_PREFIX_PATH，type为PATH，
value为D:\Qt\Qt5.6.0\5.6\mingw49_32
16.点击Configure，如果出错，点击Ungrouped Entries->QT_VTK_VERSION，改变value为5，再次点击Configure
17.等再无红颜色提示，点击Generate。
18.通过cmd到F:\VTK-7.1\VTK-bin下，使用mingw32-make
19.成功后使用mingw32-make install可生成使用的头文件和库
在qt designer中使用QVTKWidget
拷贝F:\VTK-7.1\mingw\plugins\designer文件夹中的.dll到
D:\Qt\Qt5.6.0\5.6\mingw49_32\plugins\designer
D:\Qt\Qt5.6.0\Tools\QtCreator\bin\plugins\designer
在qt中引入
在.pro中加入
