使用-isystem代替-I与CMake的 [英] Use -isystem instead of -I with CMake

问题描述

是否有任何的CMake办法强迫通过include_directories规定（或者通过不同的功能）的路径与海湾合作委员会建立时使用的-isystem标志，而不是-I标志呢？

Is there any way in CMake to force a path specified via include_directories (or perhaps through a different function) to use the -isystem flag instead of the -I flag when building with gcc?

请参阅http://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html#Directory-Options关于-I和细节-isystem。

See http://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html#Directory-Options for details on -I and -isystem.

推荐答案

是的，你强制路径是一个系统，包括通过使用可选的系统标志

Yes you force a path to be a system include by using the optional SYSTEM flag

include_directories(SYSTEM path)

与CMake的2.8.12开始，你可以使用新的target_include_directories包括系统目录包括在目标水平，同时利用cmake的新的使用要求的特点：

Starting with CMake 2.8.12 you can use the new target_include_directories to include system directory includes at the target level, while leveraging the new usage requirement features of cmake:

target_include_directories(foo SYSTEM PUBLIC path)

现在的目标foo将使用路径作为一个系统包括，和任何链接
富也将作为自动系统包括使用路径。您可以通过改变PUBLIC关键字私人或接口控制这些使用需求的传播。

Now target foo will use path as a system include, and anything that links to foo will also use path as automatically as a system include. You can control the propagation of these usage requirements by changing the PUBLIC keyword to PRIVATE or INTERFACE.
