How can I obtain gtest version 1.15.2

[CaoHaiming2024]

I am trying to install gtest in my image using the command xrepo install -y gtest, but this command installs version 1.17.0 by default.

I would like to install gtest 1.15.2 instead. However, when I run xrepo install -y gtest 1.15.2, it reports that this version does not exist.

What is the correct way to obtain or install gtest version 1.15.2 using xrepo?
