How do I avoid references to absolute paths in the generated makefile? (for linked source files) [message #1148255]

Does the "Expand Env. Variable Refs in Makefiles" actually work? or do I misunderstand it's purpose?

Basically what I want to do is using the generated Makefile for building my source on a build server, and avoiding having to manually keeping the makefile and the eclipse project settings in sync.

I've added source files to my project as links to paths outside of my project/workspace root.

In the .project file it stores the links using eclipse environment variables like "PARENT-1-WORKSPACE_LOC", which was the default behavior. I think I have also tried referencing it relative to the project root, and finally I created a custom env variable.

The result is always the same, in the generated subdir.mk it always expands the environment variable to it's absolute location:

CPP_SRCS += \
/media/sf_sharedFolder/ProjectA/Source/Test.cpp \
/media/sf_sharedFolder/ProjectB/Source/Test.cpp \
...
(I changed the path names for this example)

I thought that maybe I could use the "Expand Env. Variable Refs in Makefiles" option to prevent Eclipse from expanding this environment variables, in order to define it differently on my build server.

Is this approach valid? Or can you recommend a different one?
