Barrier: gmock and gtest missing

[autotoxicus]

Operating Systems

Raspian

Barrier Version

2.3.3

Steps to reproduce bug

I'm trying to compile your program on my RaspberryPi and cmake . is giving me two error messages.

Cannot Find Source File:
../../ext/gmock/src/gmock-all.cc

and

Cannot Find Source File:
../../ext/gtest/src/gtest-all.cc

Indeed, the folders gmock and gtest are empty in the source.

Other information

I'm following this information for compiling https://github.com/debauchee/barrier/issues/41#issuecomment-392900982 , but the command for git clone is giving me an error message.

Permission denied (public key).
fatal: Could not read from remote repository.

Please make sure you have correct access rights and the repository exists.

So I did simply clone the source as I have done it every time so far with git clone 'web adress of repository'. Perhaps this could be the reason for this problem?

You need to run git submodule init and git submodule update before compiling.

Thanks you for the quick help. I will give that a try tomorrow and report back afterwards.

Are btw different versions compatible with each other? I would then have 2.3.3 on my RaspberryPi, but my Desktop and Notebook have 2.3.2 from the package manager.

I've got it working! Thanks a lot for your help and this great tool.

And to answer my own question from the post before:
The two different versions are working fine together.

I have the same error.
The solution is not valid since I am trying to compile the release tarball, and there is no git folder.
