Question

我正在移植一个我已经工作了2年的C ++项目到Windows，我正面临这个链接问题，我在任何google引用的帖子上都没有看到......：/

这是一个CMake生成的项目，我将这些CMake条目默认设置为“\ machine：x64”

CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS

我尝试删除该标志，这对最后3个条目中的任何一个都没有影响，但是没有此值的CMAKE_EXE_LINKER_FLAGS会在我的库中传播大约85个未解析的外部因素。

我的所有项目/项目依赖项都是使用x64中的MSVC2015编译的。在调试和调试中链接都失败了发布模式（不重要..）

我还应该提一下，我在这个解决方案中有6个项目，4个库，2个可执行文件。其中4个项目编译正常（1个可执行文件和4个库），只有最后2个项目失败（两者都有相同的链接错误）。

依赖关系方面的唯一区别是对Point Cloud Library（pcl）和Qt5（Core GUI，XML和OpenGL）的依赖

有没有人遇到过这个特定的链接器错误？

希望你能帮忙=）

编辑：以下是两个主要的CMakelists文件（项目根目录的文件和编译两个失败项目的文件）。我删除了所有与此问题无关的内容。
