Fixes the following errors:

There were already some checks for _MSC_VER in the code, so this commit
continues in that vein.
If REGISTER_TYPED_TEST_CASE_P is included in a header file, but
the .cc file does not declare INSTANTIATE_TYPED_TEST_CASE_P, an
unused-variable warning may be raised by the compiler.
googletest doesn't currently build with clang's very aggressive
-Wformat-nonliteral warning. It requires that all non-literal format
strings come from the argument of a function annotated with a compatible
format attribute.
Fixing that reports that ColoredPrintf's callers weren't passing the
normal -Wformat warning. Some messages were passed directly into the
format string rather than via "%s".
Adds instructions for how to add gtest and gmock to
another CMake project directly. Downloading of the
googletest sources happens as configure time, allowing
it to be added to the main build directly via the
add_subdirectory() command. This ensures googletest is
built with the same compiler settings, etc. and will
typically result in a more robust and more convenient
build arrangement.
