[Build error] When I build this project on Ubuntu18.04LTS, it will fail

[ykk136]

Thanks for your great software. I encounter some issues when I build this project on Ubuntu18.04 LTS.

1. Firstly, I use "cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .." to get required cmake dependencies, and then use "cmake --build ." to build this project, but so many errors occur just like:

2. Secondly, I clean the build directory, and use "cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DKLOGG_USE_HYPERSCAN=OFF ..", and I can build it successfully, but when I open a log file, it will crash and output segmentation fault.
