在VS2010中，是否存在用于私有标头和库的正确位置？

Question

我应该在哪里放置.h和.lib文件，以便仅编写#include <mylib.h> （或"mylib.h" ），并且编译器和链接器将为我的所有 c ++项目找到它们？

Answer 1

There is no one single place on the computer where you can put .h / .lib files and expect them to be included in all C++ projects. The directories which are searched for .h / .lib files is a completely configurable item. Hence there is no one true include directory.

A potential option is changing the global MSBuild files for the machine. C++ projects inherit a portion of their settings from this file and it could be used to force down a set of includes to the vast majority of projects. However it's a bit of a sledge hammer option and won't be 100% effective. Any individual project can still override these defaults (or simply not use MSBuild).

It is possible though to have a unified .h / .lib directory on your machine and then manually point every C++ project at that directory

• Right click on the C++ project
• Navigate to Configuratin Properties -> C/C++ -> Command Line
• Add /I c:\\path\\to\\unified\\include
