| 8 | .. deprecated:: 3.16 |
| 9 | |
| 10 | Use :command:`file(GET_RUNTIME_DEPENDENCIES)` instead. |
| 11 | |
| 12 | Functions to analyze and list executable file prerequisites. |
| 13 | |
| 14 | This module provides functions to list the .dll, .dylib or .so files |
| 15 | that an executable or shared library file depends on. (Its |
| 16 | prerequisites.) |
| 17 | |
| 18 | It uses various tools to obtain the list of required shared library |
| 19 | files: |
| 20 | |
| 21 | :: |
| 22 | |
| 23 | dumpbin (Windows) |
| 24 | objdump (MinGW on Windows) |
| 25 | ldd (Linux/Unix) |
| 26 | otool (Mac OSX) |
| 27 | |
| 28 | .. versionchanged:: 3.16 |
| 29 | The tool specified by ``CMAKE_OBJDUMP`` will be used, if set. |
| 30 | |
| 31 | The following functions are provided by this module: |
| 32 | |
| 33 | :: |
| 34 | |
| 35 | get_prerequisites |
| 36 | list_prerequisites |
| 37 | list_prerequisites_by_glob |
| 38 | gp_append_unique |
| 39 | is_file_executable |
| 40 | gp_item_default_embedded_path |
| 41 | (projects can override with gp_item_default_embedded_path_override) |
| 42 | gp_resolve_item |
| 43 | (projects can override with gp_resolve_item_override) |
| 44 | gp_resolved_file_type |
| 45 | (projects can override with gp_resolved_file_type_override) |
| 46 | gp_file_type |
| 47 | |
| 48 | :: |
| 49 | |
| 50 | GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse> |
| 51 | <exepath> <dirs> [<rpaths>]) |
| 52 | |
| 53 | Get the list of shared library files required by <target>. The list |
| 54 | in the variable named <prerequisites_var> should be empty on first |
| 55 | entry to this function. On exit, <prerequisites_var> will contain the |
| 56 | list of required shared library files. |
| 57 | |
| 58 | <target> is the full path to an executable file. <prerequisites_var> |
| 59 | is the name of a CMake variable to contain the results. |
| 60 | <exclude_system> must be 0 or 1 indicating whether to include or |
| 61 | exclude "system" prerequisites. If <recurse> is set to 1 all |
| 62 | prerequisites will be found recursively, if set to 0 only direct |
| 63 | prerequisites are listed. <exepath> is the path to the top level |
| 64 | executable used for @executable_path replacement on the Mac. <dirs> is |
| 65 | a list of paths where libraries might be found: these paths are |
| 66 | searched first when a target without any path info is given. Then |
| 67 | standard system locations are also searched: PATH, Framework |
| 68 | locations, /usr/lib... |
| 69 | |
| 70 | .. versionadded:: 3.14 |
| 71 | The variable GET_PREREQUISITES_VERBOSE can be set to true to enable verbose |
| 72 | output. |
| 73 | |
| 74 | :: |
| 75 | |
| 76 | LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]]) |
| 77 | |
| 78 | Print a message listing the prerequisites of <target>. |
| 79 | |
| 80 | <target> is the name of a shared library or executable target or the |
| 81 | full path to a shared library or executable file. If <recurse> is set |
| 82 | to 1 all prerequisites will be found recursively, if set to 0 only |
| 83 | direct prerequisites are listed. <exclude_system> must be 0 or 1 |
| 84 | indicating whether to include or exclude "system" prerequisites. With |
| 85 | <verbose> set to 0 only the full path names of the prerequisites are |
| 86 | printed, set to 1 extra information will be displayed. |
| 87 | |
| 88 | :: |
| 89 | |
| 90 | LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>) |
| 91 | |
| 92 | Print the prerequisites of shared library and executable files |
| 93 | matching a globbing pattern. <glob_arg> is GLOB or GLOB_RECURSE and |
| 94 | <glob_exp> is a globbing expression used with "file(GLOB" or |
| 95 | "file(GLOB_RECURSE" to retrieve a list of matching files. If a |
| 96 | matching file is executable, its prerequisites are listed. |
| 97 | |
| 98 | Any additional (optional) arguments provided are passed along as the |
| 99 | optional arguments to the list_prerequisites calls. |
| 100 | |
| 101 | :: |
| 102 | |
| 103 | GP_APPEND_UNIQUE(<list_var> <value>) |
| 104 | |
| 105 | Append <value> to the list variable <list_var> only if the value is |
| 106 | not already in the list. |
| 107 | |
| 108 | :: |
| 109 | |
| 110 | IS_FILE_EXECUTABLE(<file> <result_var>) |
| 111 | |
| 112 | Return 1 in <result_var> if <file> is a binary executable, 0 |
| 113 | otherwise. |
| 114 | |
| 115 | :: |
| 116 | |
| 117 | GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>) |
| 118 | |
| 119 | Return the path that others should refer to the item by when the item |
| 120 | is embedded inside a bundle. |
| 121 | |
| 122 | Override on a per-project basis by providing a project-specific |
| 123 | gp_item_default_embedded_path_override function. |
| 124 | |
| 125 | :: |
| 126 | |
| 127 | GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var> |
| 128 | [<rpaths>]) |
| 129 | |
| 130 | Resolve an item into an existing full path file. |
| 131 | |
| 132 | Override on a per-project basis by providing a project-specific |
| 133 | gp_resolve_item_override function. |
| 134 | |
| 135 | :: |
| 136 | |
| 137 | GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var> |
| 138 | [<rpaths>]) |
| 139 | |
| 140 | Return the type of <file> with respect to <original_file>. String |
| 141 | describing type of prerequisite is returned in variable named |
| 142 | <type_var>. |
| 143 | |
| 144 | Use <exepath> and <dirs> if necessary to resolve non-absolute <file> |
| 145 | values -- but only for non-embedded items. |
| 146 | |
| 147 | Possible types are: |
| 148 | |
| 149 | :: |
| 150 | |
| 151 | system |
| 152 | local |
| 153 | embedded |
| 154 | other |
| 155 | |
| 156 | Override on a per-project basis by providing a project-specific |
| 157 | gp_resolved_file_type_override function. |

| 159 | :: |
| 160 | |
| 161 | GP_FILE_TYPE(<original_file> <file> <type_var>) |
| 162 | |
| 163 | Return the type of <file> with respect to <original_file>. String |
| 164 | describing type of prerequisite is returned in variable named |
| 165 | <type_var>. |
