The existing test harness is a homemade shell script. All the tests and the expected results are written in plain text files. The harness just reads in a test, invoke the glslangValidator binary on it, and compare the result with the golden file. All tests are kinda integration tests. This patch add Google Test as an external project, which provides a new harness for reading shader source files, compile to SPIR-V, and then compare with the expected output.
