compilation issue with google test

[pythonmobile]

Perhaps there are compilation instructions somewhere that I missed for C++?

CMake Error at CMakeLists.txt:214 (add_subdirectory):
  add_subdirectory given source "/tmp/Clipper2/CPP/Tests/googletest/" which
  is not an existing directory.


CMake Error at CMakeLists.txt:215 (set_target_properties):
  set_target_properties Can not find target to add properties to: gtest

CMake creates both the Tests and googletest folders in my Windows PC without any problems.
Unfortunately I don't know how to improve CMake to force this on your (?Linux) PC.
My only suggestion is to create these two folders manually and then reloading the CMake script.

Note that as of #745, googletest is no longer a submodule (rationale). So you may need to clone it separately?

cd CPP/Tests
git clone https://github.com/google/googletest

Thanks Juha. I'll add this as a comment into the CMake file.

In addition, guessing it ought to be possible to make CMake do this automatically. I could have a look into that – but if someone wants to do it before I get to it, no problem for me. :)
