[Bug]: Undeclared GOOGLETEST_VERSION variable causes CMake build failure

[jeffmachyo]

Describe the issue

When following the instructions as per this readme: https://github.com/google/googletest/blob/main/googletest/README.md I noticed that there is a variable known as GOOGLETEST_VERSION used in line 50 of the CMakeLists.txt but this variable is not declared anywhere in the file causing the build to fail. Once the user declares this variable, the build succeeds. Is it possible to update your documentation to advise users to manually specify the GOOGLETEST_VERSION variable?

Steps to reproduce the problem

Variable GOOGLETEST_VERSION used in Line 50 but is not declared causing the build to fail.

Same here, both googletests and googlemock needs to be built with cmake .. -DGOOGLETEST_VERSION=1.13.0
