I'd like gcc to include files from $HOME/include in addition to the usual include directories, but there doesn't seem to be an analogue to $LD_LIBRARY_PATH.
我希望gcc包含来自$HOME/包含的文件，除了通常包含的目录之外，但是似乎没有一个类似于$LD_LIBRARY_PATH的类似物。
I know I can just add the include directory at command line when compiling (or in the makefile), but I'd really like a universal approach here, as in the library case.
我知道在编译时(或者在makefile中)，我可以在命令行中添加include目录，但是我非常喜欢这里的通用方法，就像在library case中一样。

Try setting C_INCLUDE_PATH (for C header files) or CPLUS_INCLUDE_PATH (for C++ header files).
尝试设置C_INCLUDE_PATH(用于C头文件)或CPLUS_INCLUDE_PATH(用于c++头文件)。
As * mentioned, CPATH will set the path for both C and C++.
如*所述，CPATH将为C和c++设置路径。

A gcc spec file can do the job, however all users on the machine will be affected.
gcc规范文件可以完成任务，但是机器上的所有用户都会受到影响。
