llvm-cov ignore file regex does not work on windows
I have a large c++ Project which contains serveral shared objects using cmake. I am using gtest and gmock for unit tests and in addition I am using a code coverage extension from here https://github.com/StableCoder/cmake-scripts.git. The code coverage module works with gcc and clang. In addition I modified the script to be able to create code coverage on windows using cmakes -T clang-cl option (clang 17). This works quite well.
