我正在做一个DICOMViewer小项目，由于VTK本身的vtkDICOMImageRead不支持压缩格式，因此我又打了一个GDCM（3.2.1版本，cmake是3.29.2）的三方库，用于读取dicom文件，但是在正式项目却用不了，说什么没有.dll文件（我看了一下bin文件夹，还真没有），不知道哪里出了问题，网上找了一圈也没找到，麻烦各位大佬看一看，万分感谢。 1.首先是cmake编译：

点击Configure之后的配置：

后续的VS构建以及安装都没有报错，最后也是成功生成了相关文件：

项目中我是放在了这：

使用的话主要是在civMain中使用的：

写在项目中的代码没有报红，按住ctrl也是能正常进去的：
