Problem: googletest is also installed into install destination

kurdybacha · kurdybacha · commit 131d2ec4875d · 2018-04-29T12:57:32.000+01:00
Building and installing cppzmq brings googletest build artifacts to the
installation destination as well. For example someone building cppzmq
with:
```
cmake -DCMAKE_INSTALL_PREFIX=mydest .
cmake --build --target install
```
gets googletest headers and libraries in `mydest`.

Solution: remove googletest from install target
diff --git a/tests/cmake/googletest.cmake b/tests/cmake/googletest.cmake
