CMAKE_ENABLE_EXPORTS
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
Specify whether an executable exports symbols for loadable modules.
|
||
|
|
|
||
|
|
Normally an executable does not export any symbols because it is the
|
||
|
|
final program. It is possible for an executable to export symbols to
|
||
|
|
be used by loadable modules. When this property is set to true CMake
|
||
|
|
will allow other targets to "link" to the executable with the
|
||
|
|
:command:`TARGET_LINK_LIBRARIES` command. On all platforms a target-level
|
||
|
|
dependency on the executable is created for targets that link to it.
|
||
|
|
For DLL platforms an import library will be created for the exported
|
||
|
|
symbols and then used for linking. All Windows-based systems
|
||
|
|
including Cygwin are DLL platforms. For non-DLL platforms that
|
||
|
|
require all symbols to be resolved at link time, such as Mac OS X, the
|
||
|
|
module will "link" to the executable using a flag like
|
||
|
|
"-bundle_loader". For other non-DLL platforms the link rule is simply
|
||
|
|
ignored since the dynamic loader will automatically bind symbols when
|
||
|
|
the module is loaded.
|
||
|
|
|
||
|
|
This variable is used to initialize the target property
|
||
|
|
:prop_tgt:`ENABLE_EXPORTS` for executable targets.
