Hey,

seems like the project for now is not compilable? Here is the error message:

Thanks for your report. Which compiler have you used?

[botoph4]

Hey @kimkulling,

I am using GCC 11.2.0 x86_64-linux-gnu on Ubuntu 22.04

[kimkulling]

This issue is caused by a not used variable in gtest. You can disable the tests to workaound this issue:

cmake CMakeLists.txt -DCPPCORE_BUILD_UNITTESTS=OFF

I am working on a solution which will fix this issue in the correct way.
