Building / tests fail on missing Cmake in gtest

In ref to review openjournals/joss-reviews#3743
Describe the bug
Building/executing gtest fails, perhaps I missed something in the build instructions ?

To Reproduce
(after git clone, note I set CUDA to OFF in CMakeLists.txt

❯ mkdir build
❯ cd build
❯ ls
❯ cmake ..

@bencardoen Hi, thank you for your issue.

If I understand correctly, you have to init git submodules git submodule update --init --recursive rigth after the repo is cloned. Please, refer to the getting started file (you can ommit sections with CUDA related stuff if you build without CUDA backend)

@EgorOrachyov Sorry, I missed that, I should have read the instructions more carefully.
