This is set automatically based on the file extension and is used by CMake to determine if certain dependency information should be computed. + +By setting this property to ``ON``, you can disable compilation of +the given source file, even if it should be compiled because it is +part of the library's/executable's sources. + +This is useful if you have some source files which you somehow +pre-process, and then add these pre-processed sources via +:command:`add_library` or :command:`add_executable`. Normally, in IDE, +there would be no reference of the original sources, only of these +pre-processed sources. So by setting this property for all the original +source files to ``ON``, and then either calling :command:`add_library` +or :command:`add_executable` while passing both the pre-processed +sources and the original sources, or by using :command:`target_sources` +to add original source files will do exactly what would one expect, i.e. +the original source files would be visible in IDE, and will not be built. |
