vs2019编译flann 编译后没有flann_cpp.lib和flann_cpp-gd.lib

在 VS2019 中编译 flann 库时，需要进行以下步骤：

1. 打开 flann.sln 解决方案文件。
2. 选择 Release 或 Debug 配置，然后右键单击 flann_cpp 应用程序项目，选择“属性”。
3. 在“属性页”中，选择“常规”，然后选择“输出目录”和“中间目录”，确保这些路径指向你想要的目录。
4. 在“C/C++”->“常规”下，将“附加包含目录”设置为 flann 库头文件所在的路径。
5. 在“链接器”->“常规”下，将“附加库目录”设置为 flann 库 lib 文件所在的路径。
6. 在“链接器”->“输入”下，将“附加依赖项”设置为 flann_cpp.lib 或 flann_cpp-gd.lib。
7. 最后，右键单击 flann_cpp 应用程序项目，选择“生成”。

如果你按照以上步骤进行编译，但仍然没有生成 flann_cpp.lib 和 flann_cpp-gd.lib 文件，可能是你的编译选项不正确。你可以检查一下编译选项是否正确，并根据需要进行修改。

这个错误表示在构建 PCL 时，CMake 找不到 VTK 库的某些模块，具体是 `vtkRenderingOpenGL2` 和 `vtkRenderingContextOpenGL2`。这可能是由于 VTK 没有正确安装或安装位置不正确导致的。你可以尝试重新安装 VTK 并确保路径正确，或者在 CMake 的配置中指定 VTK 库的路径。你也可以检查 `VTKTargets.cmake` 文件是否存在，并且文件路径是否正确。另外，CMake 还需要安装 ClangFormat 14 或更高版本，你可以在系统上安装该版本的 ClangFormat 或在 CMake 的配置中禁用 ClangFormat。如果问题仍然存在，请提供更多的详细信息，以便我能够更好地帮助你解决问题。
