PROJ/test/googletest, branch rfc4_dev

Update internal version of googletest to v1.8.1

2019-03-24T19:45:54+00:00

This is already what is used by cmake builds

Use GTest 1.8.1

2019-02-14T15:52:57+00:00

This fixes issues with MinGW when threads are used.

Don't install gtest libraries.

Add CMakeLists.txt.in to EXTRA_DIST of test/googletest/Makefile.am

Add CMake configuration for test/googletest and test/unit

2018-06-07T19:21:49+00:00

For CMake builds, latest googletest 1.8.0 is downloaded.

Following officially recommended integration for CMake-enabled projects
https://github.com/google/googletest/blob/master/googletest/README.md

  "Use CMake to download GoogleTest as part of the build's configure step.
  This is just a little more complex, but doesn't have the limitations
  of the other methods."

Since, our copy of test/googletest
- is a very minimalist copy of googletest
- does not include any official CMake scripts
- would require copying parts of googletest CMakeLists.txt, compilater/linker flags (e.g. -lpthreads)
for reliable multi-platform builds, it is reasoanable to rely on download
All pros and cons advantages are discussed in teh README.md linked above.

Closes #1033

Add googletest 1.8.0 framework in test/googletest, and use it with autoconf builds only (CMake integration to be done)
