Error when trying to install blocktest

[martinaxgloria]

I was trying to install this repo following the instructions in the README.md but I retrieved the following error:

/home/mgloria/iit/blocktest/build/_deps/unittest-src/googletest/src/gtest-death-test.cc: In function ‘bool testing::internal::StackGrowsDown()’:

This seems an error related to gtest, not this repo. Looking at the gtest issues, I found that a lot of people have experienced this bug and this happens with gcc version 11.x and googletest v1.10 (which I think is the version used in here). This issue got fixed by this PR and the fix is available since gtest v1.11.0.

To correctly install BlockTest, maybe it is sufficient to update the GIT_TAG argument of the FetchContent_Declare call.
