[cdt-dev] What is the way to set include paths so they survive a project

[Jan Baeyens <jan@xxxxxxxxxx>]

Hi
The arduino environment relies heavily on libraries. Libraries are a set 
of source code delivered by others.
As to not mangle code I use a include paths for each and every library. 
Given that this is for C, C++ and assembly that is a big list of include 
paths.

Now Someone noticed that when you rename a project the includes paths 
are not modified.
If I use the gui to include a workspace folder of the project "test" I 
get "/test/libraries/library" and it is marked as workspace path.
My code generates the same using following method
            ICLanguageSettingEntry[] OrgIncludeEntries = 
lang.getSettingEntries(ICSettingEntry.INCLUDE_PATH);
            ICLanguageSettingEntry[] IncludeEntries = new 
ICLanguageSettingEntry[OrgIncludeEntries.length + 1];
            System.arraycopy(OrgIncludeEntries, 0, IncludeEntries, 0, 
OrgIncludeEntries.length);
            IncludeEntries[OrgIncludeEntries.length] = new 
CIncludePathEntry(IncludePath, ICSettingEntry.VALUE_WORKSPACE_PATH);

where IncludePath equals "/test/libraries/library"

In both cases after renaming the project the include paths become invalid.
I tried using ${ProjName} but that seems to be incompatible with 
"workspace path"

So I was wondering: How do I add a folder to the include path in such a 
way the project can still be compiled/indexed after a rename?

Best regards
