when bazel running a cc_binary in Windows, the C++ app can't find its data dependencies

[thinlizzy]

Please provide the following information. The more we know about your system and use case, the more easily and likely we can help.

Description of the problem / feature request / question:

I have a cc_binary rule with a single .cpp file and one data dependency. I have no means to tell the application where to find the data.

If possible, provide a minimal example to reproduce the problem:

BUILD file in engine_test/demos directory relative to the WORKSPACE directory

cc_binary(
	name = "test",
	srcs = [
		"Test.cpp",
	],
	data = ["//engine_test/images"],
)

BUILD file in engine_test/images directory. same deal

filegroup(
    name = "images",
    srcs = glob([
        "*.png",
    ]),
)

Test.cpp

#include <fstream>

int main()
{
  std::fstream fs("engine_test/images/test.png");  // can't find the file
  // fs.fail() == true   :(
}

Environment info

• Operating System: Windows
• Bazel version (output of bazel info release): release 0.5.4

Have you found anything relevant by searching the web?

#3881 seems to be related, but I also tried to use ($location //engine_test/images) without success.

Anything else, information or logs or outputs that would be helpful?

my current workaround to open the files is:
std::fstream fs("../../../../../../engine_test/images/test.png");

CC: @laszlocsomor Do you know why this doesn't work on Windows?
