fatal error: dcmtk/config/osconfig.h: No such file or directory

Question

作为 CMake 新手，我正在拼命尝试让 DCMTK 做一些事情。我正在尝试编译的示例运行如下：

#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"
#include "dcmtk/dcmdata/dcistrmf.h"

int main(int argc, char *argv[])
{
    OFCondition status;

    /* approach 1 */
    DcmMetaInfo metainfo;
    status = metainfo.loadFile("test.dcm");
    if (status.good())
    {
        OFString sopClassUID, xferUID;
        if (metainfo.findAndGetOFString(DCM_MediaStorageSOPClassUID, sopClassUID).good())
            COUT << "SOP Class UID: " << sopClassUID << OFendl;
        if (metainfo.findAndGetOFString(DCM_TransferSyntaxUID, xferUID).good())
            COUT << "Transfer Syntax UID: " << xferUID << OFendl;
        metainfo.print(COUT);
    }

    /* approach 2 */
    DcmFileFormat fileformat;
    status = fileformat.loadFile("test.dcm", EXS_Unknown, EGL_noChange, DCM_MaxReadLength, ERM_metaOnly);
    if (status.good())
    {
        OFString sopClassUID, xferUID;
        if (fileformat.getMetaInfo()->findAndGetOFString(DCM_MediaStorageSOPClassUID, sopClassUID).good())
            COUT << "SOP Class UID: " << sopClassUID << OFendl;
        if (fileformat.getMetaInfo()->findAndGetOFString(DCM_TransferSyntaxUID, xferUID).good())
            COUT << "Transfer Syntax UID: " << xferUID << OFendl;
        fileformat.print(COUT);
    }

    /* approach 3 */
    fileformat.clear();
    DcmInputFileStream fileStream("test.dcm");
    status = fileStream.status();
    if (status.good())
    {
        /* first, read meta-header */
        fileformat.setReadMode(ERM_metaOnly);
        fileformat.transferInit();
        status = fileformat.read(fileStream);
        if (status.good())
        {
            OFString sopClassUID, xferUID;
            if (fileformat.getMetaInfo()->findAndGetOFString(DCM_MediaStorageSOPClassUID, sopClassUID).good())
                COUT << "SOP Class UID: " << sopClassUID << OFendl;
            if (fileformat.getMetaInfo()->findAndGetOFString(DCM_TransferSyntaxUID, xferUID).good())
                COUT << "Transfer Syntax UID: " << xferUID << OFendl;
            /* then read dataset if certain criteria are met */
            if (sopClassUID == UID_SecondaryCaptureImageStorage)
            {
                fileformat.setReadMode(ERM_autoDetect);
                status = fileformat.read(fileStream);
                if (status.good())
                {
                    fileformat.print(COUT);
                }
            }
        }
        fileformat.transferEnd();
    }

    return 0;
}

问题出在这个文件的上半部分。我知道在特定文件夹中，此代码将出现构建错误，因为它不会在项目目录中找到 dcmtk 文件夹。我已经在驱动器上其他地方的不同文件夹中构建并安装了 DCMTK。因此我有两个文件夹：dcmtk-3.6.5-build 和 dcmtk-3.6.5-install。我知道我感兴趣的是dcmtk-3.6.5-install/include/。但是在构建时出现以下错误：

====================[ Build | test_dcmtk | Debug ]==============================

make[1]: *** [CMakeFiles/Makefile2:103: CMakeFiles/test_dcmtk.dir/rule] Error 2
make: *** [Makefile:138: test_dcmtk] Error 2

按我的理解，我应该将编译器指向安装DCMTK的目录。但是当我这样做时，我得到了一个非常相似的错误：

====================[ Build | test_dcmtk | Debug ]==============================
/snap/clion/139/bin/cmake/linux/bin/cmake --build /home/project_dir/test_dcmtk/cmake-build-debug --target test_dcmtk -- -j 38

这两个错误的区别在于编译器寻找的 headers。在第二种情况下，编译器似乎不理解 osconfig.h 在哪里。由于这涉及来自 DCMTK 安装的文件，我的理解是它们应该按原样工作，这让我想到应该用 CMake 解决这个问题。但是我完全不知道如何在我的 CMakeLists.txt 中做正确的事情......我的意思是说这个文件包含

cmake_minimum_required(VERSION 3.16)
project(test_dcmtk)

set(CMAKE_CXX_STANDARD 20)

add_executable(test_dcmtk main.cpp)

而且我完全不知道在这里写什么。有人可以帮我吗？

提前致谢！

遗憾的是，DCMTK 不提供正确导出的 CMake 目标，因此您将不得不对其进行修补。我通过 vcpkg 安装了 DCMTK，并且能够使用此版本编译您的代码（在将 COUT 替换为 std::cout 并包括 iostream 之后）：

cmake_minimum_required(VERSION 3.19)
project(test_dcmtk)

set(CMAKE_CXX_STANDARD 20)

find_package(DCMTK REQUIRED)

# Wrap the variables that DCMTK sets with a proper imported target
# These three lines ought not to be needed.
# This is a failure on the part of the DCMTK authors.
add_library(DCMTK::DCMTK INTERFACE IMPORTED)
target_link_libraries(DCMTK::DCMTK INTERFACE ${DCMTK_LIBRARIES})
target_include_directories(DCMTK::DCMTK INTERFACE ${DCMTK_INCLUDE_DIRS})

# Create your executable and link it to the library
add_executable(test_dcmtk main.cpp)
target_link_libraries(test_dcmtk PRIVATE DCMTK::DCMTK)

您应该向 DCMTK 库作者投诉他们没有提供正确的导入目标。
