Functions to analyze and list executable file prerequisites.
|
||
|
|
|
||
|
|
This module 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)
|
||
|
|
objdump (MinGW on Windows)
|
||
|
|
ldd (Linux/Unix)
|
||
|
|
otool (Mac OSX)
|
||
|
|
|
||
|
|
The following functions are provided by this module:
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
get_prerequisites

(projects can override with gp_resolve_item_override)

|
(projects can override with gp_resolved_file_type_override)
|
||
|
|
gp_file_type
|

|
|

Requires CMake 2.6 or greater because it uses function, break, return
|
||
|
|
and PARENT_SCOPE.

|
||
|
|
<exepath> <dirs> [<rpaths>])
|
||
|
|
|
||
|
|
Get the list of shared library files required by <target>. The list
|
||
|
|
in the variable named <prerequisites_var> should be empty on first
|
||
|
|
entry to this function. On exit, <prerequisites_var> will contain the
|
||
|
|
list of required shared library files.
|
||
|
|
|
||
|
|
<target> is the full path to an executable file. <prerequisites_var>
|
||
|
|
is the name of a CMake variable to contain the results.
|
||
|
|
<exclude_system> must be 0 or 1 indicating whether to include or
|
||
|
|
exclude "system" prerequisites. If <recurse> is set to 1 all
|
||
|
|
prerequisites will be found recursively, if set to 0 only direct
|
||
|
|
prerequisites are listed. <exepath> is the path to the top level
|
||
|
|
executable used for @executable_path replacment on the Mac. <dirs> is
|
||
|
|
a list of paths where libraries might be found: these paths are
|
||
|
|
searched first when a target without any path info is given. Then
|
||
|
|
standard system locations are also searched: PATH, Framework
|
||
|
|
locations, /usr/lib...
|
||
|
|
|
||
|
|
The variable GET_PREREQUISITES_VERBOSE can be set to true to enable verbose
|
||
|
|
output.

LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])
|
||
|
|
|
||
|
|
Print a message listing the prerequisites of <target>.
|
||
|
|
|
||
|
|
<target> is the name of a shared library or executable target or the
|
||
|
|
full path to a shared library or executable file. If <recurse> is set
|
||
|
|
to 1 all prerequisites will be found recursively, if set to 0 only
|
||
|
|
direct prerequisites are listed. <exclude_system> must be 0 or 1
|
||
|
|
indicating whether to include or exclude "system" prerequisites. With
|
||
|
|
<verbose> set to 0 only the full path names of the prerequisites are
|

printed, set to 1 extra informatin will be displayed.

LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)
|
||
|
|
|
||
|
|
Print the prerequisites of shared library and executable files
|
||
|
|
matching a globbing pattern. <glob_arg> is GLOB or GLOB_RECURSE and
|
||
|
|
<glob_exp> is a globbing expression used with "file(GLOB" or
|
||
|
|
"file(GLOB_RECURSE" to retrieve a list of matching files. If a
|
||
|
|
matching file is executable, its prerequisites are listed.
|
||
|
|
|
||
|

Any additional (optional) arguments provided are passed along as the

optional arguments to the list_prerequisites calls.
