Hmm, no failures with gcc build, but someone had a very similar issue elsewhere: https://stackoverflow.com/questions/46734274/c-cmake-build-with-cotire-and-gtest-error-with-float-h

Opened an issue with upstream, looks like a bug: luceneplusplus/LucenePlusPlus#199

I will just put tests into a variant. Anyway we did not have them, and without tests no errors with clang.
