1SKIP_PRECOMPILE_HEADERS 2----------------------- 3 4.. versionadded:: 3.16 5 6Is this source file skipped by :prop_tgt:`PRECOMPILE_HEADERS` feature. 7 8This property helps with build problems that one would run into 9when using the :prop_tgt:`PRECOMPILE_HEADERS` feature. 10 11One example would be the usage of Objective-C (``*.m``) files, and 12Objective-C++ (``*.mm``) files, which lead to compilation failure 13because they are treated (in case of Ninja / Makefile generator) 14as C, and CXX respectively. The precompile headers are not 15compatible between languages. 16
