[Bug]: Passing -DGTEST_HAS_RTTI=0 using cmake has no effect

[eyalgolan1337]

Describe the issue

When passing -DGTEST_HAS_RTTI=0 to cmake the value of GTEST_HAS_RTTI still ends being 1, which causes gtest to use typeid. This is obviously a problem when trying to use gtest with code that was compiled with -fno-rtti.

As a side-note, I ran into this problem when using gtest though vcpkg, so in order to define this preprocessor macro i had to add a patch to gtest's CMakeLists.txt and add add_definitions(-DGTEST_HAS_RTTI=0) because it does not support passing the options defined in gtest-port.h. Consider adding support for these options in the cmakelists file in the future so a patch is not needed and instead passing GTEST_HAS_RTTI=OFF to vcpkg_cmake_configure will be enough

Steps to reproduce the problem

try and link gtest compiled with -DGTEST_HAS_RTTI=0 into a binary compiled with -fno-rtti. The problem occurs when trying to use TYPED_TEST_SUITE()
