s2loop_test: Build fails with recent versions of abseil

EXPECT_THAT(error.text(), testing::HasSubstr(snippet));

S2 fails to build with recent versions of abseil at places where HasSubstr ist used. Replacing the string_view with a string works (as a workaround):
EXPECT_THAT(error.text(), testing::HasSubstr(std::string(snippet)));

[jmr]

Please include the error you're getting.

Is absl::string_view == std::string_view for you?

[benstadin]

Yes. Abseil is built from source using the current LTS version (git tag 20240116.1)

Same commands to compile as #356 ?

Which googletest? Does this one work with 1.14.0?

[benstadin]

Yes, same commands. Cmake actually fails with more recent versions of gtest. So this was build with 1.10.0.

The error I get with 1.14.0 versions of test is (as far as I can remember, all recent versions show the same error, and 1.11.0 showed either this error when running cmake or the same error as with v1.10.0 when compiling):

The error I get with 1.14.0 versions of test is

CMake Warning at googletest/googlemock/CMakeLists.txt:40 (project):
  VERSION keyword not followed by a value or was followed by a value that
 expanded to nothing.

What's around line 40 for you? I have:

    10  
    11  set(GOOGLETEST_VERSION 1.14.0)
    12  
...
    40  # Language "C" is required for find_package(Threads).
    41  cmake_minimum_required(VERSION 3.13)
    42  project(gmock VERSION ${GOOGLETEST_VERSION} LANGUAGES CXX C)

What's your cmake version? I have 3.28.1.

[SkyTik]

Yes, same commands. Cmake actually fails with more recent versions of gtest. So this was build with 1.10.0.

The error I get with 1.14.0 versions of test is (as far as I can remember, all recent versions show the same error, and 1.11.0 showed either this error when running cmake or the same error as with v1.10.0 when compiling):

you need to pass -DGOOGLETEST_VERSION=1.14.0 in cmake command when build googletest and s2geometry also
