Question

在发生许多模糊错误（至少对我来说）之后，我发现在尝试设置QtCreator项目文件以便与CUDA一起使用时，在Makefile.Debug和Makefile的LIBS定义中放置了一些额外的引号。发布文件。

LIBS          = /LIBPATH:"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\lib\x64" ""C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\lib\x64"\cuda.lib" ""C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\lib\x64"\cudart.lib" /LIBPATH:C:\Qt\5.2.1\msvc2012_64_opengl\lib C:\Qt\5.2.1\msvc2012_64_opengl\lib\Qt5Cored.lib

如果仔细观察LIBPATH中的第二个条目，您会在C：前面看到一个额外的引号。您还会在x64之后的字符串中间看到一个额外的引号。对于CUDA库的两个条目都会发生此异常。如果我进入这个makefile并手动更正它（删除额外的引号），项目构建并运行没有错误。

所以，我想知道如何设置项目文件来纠正这个问题。它已经老了，不得不回到makefile进行手动修复。

供参考，这是我的整个项目文件。

如果库路径中至少有一个空格，则会在Qt 5.3.0，Qt 5.3.2上复制该错误。它与Qt 5.5.1一样正常工作。

所以，有两种选择：

将Qt升级到5.5.1（某些早期版本也可以使用）;
将库移动到没有空格的完整路径的目录。

QMAKE在make文件的lib路径中添加额外的引用
