-------

|
|
|
||
|
|
Disallow install() of export() result.
|
||
|
|
|
||
|
|
The :command:`export()` command generates a file containing
|
||
|
|
:ref:`Imported Targets`, which is suitable for use from the build
|
||
|
|
directory. It is not suitable for installation because it contains absolute
|
||
|
|
paths to buildsystem locations, and is particular to a single build
|
||
|
|
configuration.
|
||
|
|
|
||
|
|
The :command:`install(EXPORT)` generates and installs files which contain
|
||
|
|
:ref:`Imported Targets`. These files are generated with relative paths
|
||
|
|
(unless the user specifies absolute paths), and are designed for
|
||
|
|
multi-configuration use. See :ref:`Creating Packages` for more.
|
||
|
|
|
||
|
|
CMake 3.3 no longer allows the use of the :command:`install(FILES)` command
|
||
|
|
with the result of the :command:`export()` command.
|
||
|
|
|
||
|
|
The ``OLD`` behavior for this policy is to allow installing the result of
|
||
|
|
an :command:`export()` command. The ``NEW`` behavior for this policy is
|
||
|
|
not to allow installing the result of an :command:`export()` command.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.3. CMake version
|
||
|
|
|release| warns when the policy is not set and uses ``OLD`` behavior. Use
|
||
|
|
the :command:`cmake_policy()` command to set it to ``OLD`` or ``NEW``
|
||
|
|
explicitly.
