Target-level dependencies will be completely finished, including their POST_BUILD if any, before the PRE_BUILD of a dependent target begins. In your list above, `LA` and `TA` will definitely be built before `B` starts. For the generated file `FA`, it depends whether the custom command is attached to `B` or not. If it is inside `B` then it won't generate until after PRE_BUILD is done. PRE_BUILD in VS means "if any files associated with this .vcxproj are about to be built due to updated dependencies or missing outputs, then run this pre-build command first". -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
