   In the Appveyor build cmake 3.17 is used, so `GTEST_USE_CONFIG` is set to `TRUE`. And as the conda package still has no Config.cmake the error occures. But as I understand the docs the [`FindGTest.cmake`](https://cmake.org/cmake/help/v3.0/module/FindGTest.html) has been available since cmake 3.0 so we could either set it to always be `FALSE` or not set it explicitly at all in which case it [would fallback](https://cmake.org/cmake/help/v3.17/command/find_package.html) to looing for `GTestConfig.cmake` if it was not able to locate Gtest via the bundled FindGtest. But I do not know if this might have unwanted repercussions on other builds. @kou ?
