gmock requires patching because it uses the same symbol exporting macro
(GTEST_API_) as gtest. This makes it impossible to have the gmock library
depend on gtest on Windows. See the following upstream bug report for
details:

https://github.com/google/googletest/issues/3738

The patching procedure is as follows:

1. Instead of symlink'ing gmock headers and source, copy them.

2. Run the following command to replace GTEST_API_ with GMOCK_API_:

find src include -name 'gmock*.h' -o -name 'gmock*.cc' | \
  xargs -n 1 sed -i -e 's/GTEST_API_/GMOCK_API_/g'

3. Copy the following fragment to include/gmock/internal/gmock-port.h
   before any existing macro definitions (this is similar to gtest-port.h):

// GMOCK_API_ qualifies all symbols that must be exported. The definitions below
// are guarded by #ifndef to give embedders a chance to define GMOCK_API_ in
// gmock/internal/custom/gtest-port.h
#ifndef GMOCK_API_

#ifdef _MSC_VER
# if GMOCK_LINKED_AS_SHARED_LIBRARY
#  define GMOCK_API_ __declspec(dllimport)
# elif GMOCK_CREATE_SHARED_LIBRARY
#  define GMOCK_API_ __declspec(dllexport)
# endif
#elif __GNUC__ >= 4 || defined(__clang__)
# define GMOCK_API_ __attribute__((visibility ("default")))
#endif  // _MSC_VER

#endif  // GMOCK_API_

#ifndef GMOCK_API_
# define GMOCK_API_
#endif  // GMOCK_API_
