Qt +VTK+Cmake 编译和环境配置（第一篇 采坑）

VTK下载地址：https://vtk.org/download/

cmake下载地址：https://cmake.org/download/

版本对应方面，如果你的项目对版本没有要求，就不用在意。我就是自己随机搭建的，VTK选择最新版本吧，如果后面其他的库不支持高版本 ，我在更好低版本的。这里只是介绍一下编译过程。

 这个最新版本9.3.0。

下载8.2.0版本

选择Source下的.zip版本，tar.gz是Linux的。cmake记得下载.     msi后缀的，这里选择64位的即win64，下载好后直接双击默认下一步安装即可。这里我们要自己编译，所以下载  VTK-8.2.0.zip这个文件。

安装好Cmake

如果选择 Qt的gcc和g++编译器，可以参考我的博客

Cmake:Error in configuration process,project files may be invalid.Qt编译opencv的经验之谈。_Vertira的博客-CSDN博客

编译VTK和 编译opencv 差别不大。

如果出现这种错误看我的连接

error: ‘std::_hypot‘ has not been declared using std::hypot；_Vertira的博客-CSDN博客

 如果没有错误，就忽略上面的连接

 

第一次Configure应该要挺长时间，5-10分钟吧，具体看电脑的处理器性能，这只是第一次，后面还有好几次，因为需要继续改参数配置，第一次的Configure过后，会出现下图所示的一片红色，这个不用担心，这里需要修改的地方有三处，分别是：

1. BUILD_EXAMPLES：生成一些vtk官方的examples，帮助理解学习，当然不选择也没事；
2. CMAKE_INSTALL_PREFIX：这里存放之后使用vtk时的一些动态库dll，二进制库lib，vtk的一些头文件之类的。图上此项的位置已经修改为 刚创建的那个vtk-pefix文件夹的路径（也可以把文件夹的路径名称改为vtk-install）；
3. VTK_Group_Qt：我这里需要在Qt中使用vtk，所以选择了此项。

 编译出错：：：：：？？？？？？？？？

这个错误网上查了一下，原来是一些文件的路径没有设置

那就在cmake界面的add Entry，把上面的路径一点一点的添加上去。

 

 

 结果出现这样的问题，

没有报错，但是执行失败？？？？？？？？？  这是什么原因呢？

我的电脑是比较老旧，显卡也是英伟达GF 525M，虽然比较老，应该不至于吧。

重新删除重新编译。试一试
