COMPILE_FLAGS和COMPILE_OPTIONS之间的区别 [英] Difference between COMPILE_FLAGS and COMPILE_OPTIONS

问题描述

What is the difference between

COMPILE_FLAGS和有什么区别？

COMPILE_FLAGS: Additional flags to use when compiling this target's sources.

和

COMPILE_OPTIONS：传递给编译器的选项列表。 / p>

COMPILE_OPTIONS: List of options to pass to the compiler.

对于最终的VS2010解决方案，这些命令产生的结果相同：

In terms of resulting VS2010 solution these commands produce the same result:

target_compile_options(target PRIVATE "/option=test1")
set_target_properties(target PROPERTIES COMPILE_FLAGS "/option=test1")
set_target_properties(target PROPERTIES COMPILE_OPTIONS "/option=test1")

推荐答案

COMPILE_OPTIONS 是一个列表，但 COMPILE_FLAGS 是一个字符串。

COMPILE_OPTIONS is a list, but COMPILE_FLAGS is a string.

set_target_properties(target PROPERTIES 
    COMPILE_OPTIONS "/option=test1;/option2=test2")
set_target_properties(target PROPERTIES 
    COMPILE_FLAGS "/option=test1 /option2=test2")

与列表相比，您可以更轻松地附加到列表。

You can more-easily append to a list than to a string.

此外， COMPILE_OPTIONS 已正确转义，而 COMPILE_FLAGS 可能需要手动转义或导致问题。

Also, COMPILE_OPTIONS is properly escaped, whereas some characters in COMPILE_FLAGS may need to be escaped manually or cause problems.
