Make：根据目标设置变量
我想根据指定的目标设置一个变量。 例如：
if target == filename_a then
VAR1 = YES
if target == filename_b then
VAR2 = YES
显然，这是伪代码，而不是正确的 make 语法。
我真正想做的是根据目标包含不同的 make 文件和包含目录。一些目标共享相同的设置，因此在一个 makefile 中维护起来更容易。
稍后将使用它的示例：
ifeq ($(VAR1), YES)
include foo.mk
endif
ifeq ($(VAR2), YES)
include baz.mk
endif
不幸的是，不能使用以下语法：
target : VAR1 = YES
因为据我所知，此变量分配仅在实际构建目标的过程中有效。
目标环境是Solaris下的ClearMake 7，因此请避免任何GNU Make特定的解决方案。
谢谢
编辑： 据我所知，make 无法以在处理步骤中目标可用的方式工作。因此，所要求的功能很可能确实存在。
I want to set a variable depending on the assigned target.
For instance:
if target == filename_a then
VAR1 = YES
if target == filename_b then
VAR2 = YES
Obviously, this is pseudo-code and not proper make-syntax.
What I really want to do is to include different make-files and include-directories dependent on target. Some targets share the same settings, and hence it is easier to maintain in one makefile.
An example of what it will be used for later:
ifeq ($(VAR1), YES)
include foo.mk
endif
ifeq ($(VAR2), YES)
include baz.mk
endif
Unfortunantly the following syntax cannot be used:
target : VAR1 = YES
Since this variable assignment is only valid through the process of actually building target, as I understand it.
The target environment is ClearMake 7 under Solaris, so please avoid any GNU Make specific solutions.
Thanks
Edit:
As far as I can tell, make does not work in a way where the target is available during the processing step. Hence the feature asked for does most likely exist.

如果这能起作用，我会感到惊讶，因为据我了解，Make 流程在知道需要制定什么目标之前包含语句。但我对 ClearMake 一无所知，而且我也不是真正的专家，所以希望有人证明我错了......
I'd be surprised if this can work, since as I understand it, Make processes include statements before it knows what targets it needs to make. But I know nothing about ClearMake and I'm not really an expert, so hopefully someone proves me wrong...
