| aux_source_directory |
| -------------------- |
| |
| Find all source files in a directory. |
| |
| :: |
| |
| aux_source_directory(<dir> <variable>) |
| |
| Collects the names of all the source files in the specified directory |
| and stores the list in the <variable> provided. This command is |
| intended to be used by projects that use explicit template |
| instantiation. Template instantiation files can be stored in a |
| "Templates" subdirectory and collected automatically using this |
| command to avoid manually listing all instantiations. |
| |
| It is tempting to use this command to avoid writing the list of source |
| files for a library or executable target. While this seems to work, |
| there is no way for CMake to generate a build system that knows when a |
| new source file has been added. Normally the generated build system |
| knows when it needs to rerun CMake because the CMakeLists.txt file is |
| modified to add a new source. When the source is just added to the |
| directory without modifying this file, one would have to manually |
| rerun CMake to generate a build system incorporating the new file. |
