CMake will +automatically escape the value correctly for the native build system +(note that CMake language syntax may require escapes to specify some +values). + +This property will be initialized in each directory by its value in the +directory's parent. + +CMake will automatically drop some definitions that are not supported +by the native build tool. The VS6 IDE does not support definition +values with spaces (but NMake does). + +.. include:: /include/COMPILE_DEFINITIONS_DISCLAIMER.txt + +Contents of ``COMPILE_DEFINITIONS`` may use "generator expressions" with +the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` +manual for available expressions. See the :manual:`cmake-buildsystem(7)` +manual for more on defining buildsystem properties. + +The corresponding :prop_dir:`COMPILE_DEFINITIONS_<CONFIG>` property may +be set to specify per-configuration definitions. Generator expressions +should be preferred instead of setting the alternative property. |
