wrong staticLibraries handling

For staticLibraries you expect 2 possible inputs: library name or absolute path.

for (i in staticLibraries) {
        if (FileInfo.isAbsolutePath(staticLibraries[i])) {
            args.push(staticLibraries[i]);
        } else {
            args.push('-l' + staticLibraries[i]);
        }

But it is not real world cases. When you configure project to be used by different people you use relative pathes.
For me it is something like:

  cpp.staticLibraries: [
			"../libs/Some3rdParty/lib/somelib.a",
			"../libs/AnotherExternal/lib/anotherlib.lib"
                        ]

or even more handy to use cpp.libraryPaths and then just list libraries.

So my suggestion is next: not use absolute path dependency, better to verify is static library contain library suffix, e.g. contains '.a' or '.lib'.
