Gtest discover_tests failing in Github Actions: Process terminated due to timeout

I am using google-test(gtest) with CMake and running the unit tests as GitHub ci jobs for Linux and Mac. The Linux jobs pass successfully. However, I am getting an error for the mac runner. The error is

CMake Error at /usr/local/Cellar/cmake/3.21.1/share/cmake/Modules/GoogleTestAddTests.cmake:77 (message):
  Error running test executable.

    Path: '/Users/runner/work/splitwebp/build/test/splitwebp_tests'
    Result: Process terminated due to timeout
    Output:

This is the CMakelists.txt for the tests directory

gtest_discover_tests(splitwebp_tests)

How do I fix the CI pipeline?

The problem is gtest_discover_tests(...) is taking too long and thus getting timed out. The obvious solution is to increase the timeout limit.

The line

gtest_discover_tests(splitwebp_tests)

can be replaced with

gtest_discover_tests(splitwebp_tests PROPERTIES TIMEOUT 600)
