SUMMARY
When attempting to build KDocTools on macOS 15.0 (Sequoia) using AppleClang 17.0.0 via kde-builder, the build fails during the compilation of `loggingcategory.cpp` and `xslt_kde.cpp`.

The error indicates a conflict between the C++ standard library headers and the macOS system SDK math headers, specifically regarding `std::isinf`, `std::isnan`, and `abs`.

STEPS TO REPRODUCE
1. Setup kde-builder on macOS 15 (Apple Silicon M-series).
2. Attempt to build kdoctools (`./kde-builder kdoctools`).
3. Build fails at cmake targeting Ninja.

OBSERVED RESULT
Compilation errors regarding "expected unqualified-id" in cmath.
