| # GetPrerequisites.cmake |
| # |
| # This script provides functions to list the .dll, .dylib or .so files that an |
| # executable or shared library file depends on. (Its prerequisites.) |
| # |
| # It uses various tools to obtain the list of required shared library files: |
| # dumpbin (Windows) |
| # ldd (Linux/Unix) |
| # otool (Mac OSX) |
| # |
| # The following functions are provided by this script: |
| # gp_append_unique |
| # is_file_executable |
| # gp_item_default_embedded_path |
| # (projects can override with gp_item_default_embedded_path_override) |
| # gp_resolve_item |
| # (projects can override with gp_resolve_item_override) |
| # gp_resolved_file_type |
| # gp_file_type |
| # get_prerequisites |
| # list_prerequisites |
| # list_prerequisites_by_glob |
| # |
| # Requires CMake 2.6 or greater because it uses function, break, return and |
| # PARENT_SCOPE. |
