Parallel processing 如何使用CMake构建用于并行计算的VTK？

我想用CMake构建VTK，用于并行计算，环境是Win10（x64）、Codeblocks-12.11、VTK-7.0.0和CMake-3.5.0。当我选择了

VTK\u Group\u MPI

和

Module\u vtkParallelMPI

时，CMake错误如下。那么，如何使用CMake构建用于并行计算的VTK呢？提前谢谢你

我必须承认，我自己没有尝试构建VTK，但我知道足够多的CMake发现它找不到MPI库，因为变量MPI_C_LIBRARIES和MPI_HEADER_PATH没有设置

您如何配置CMake

如果您正在使用CMake GUI（我建议您这样做），您应该打开分组和高级选项

现在，Find\u MPI CMake脚本使用注册表来查找MPI库-因此您可以通过设置

MSMPI\u BIN

环境变量来帮助它

看

但是，如果所有这些都是太多的黑魔法，那么您只需在CMake中为缺少的变量输入正确的值，前提是您已打开高级和分组模式。

将MPI二进制文件目录添加到您的路径

PATH=$PATH:${YOU_MPI_DIRECTORY}/bin

MPI编译器、mpicc、mpicxx、mpif90等都是应该解决这些依赖关系的包装器
