IMPORTED Targets
|
|
|
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 3.21
|
|
|
|
|
|
|
|
|
|
This module defines the :prop_tgt:`IMPORTED` targets:
|
|
|
|
|
|
|
|
|
|
``DevIL::IL``
|
|
|
|
|
Defined if the system has DevIL.
|
|
|
|
|
|
|
|
|
|
``DevIL::ILU``
|
|
|
|
|
Defined if the system has DevIL Utilities.
|
|
|
|
|
|
|
|
|
|
``DevIL::ILUT``
|
|
|
|
|
Defined if the system has DevIL Utility Toolkit.
|
|
|
|
|
|
|
|
|
|
Result Variables
|
|
|
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
This module sets:
|
|
|
|
|
|
|
|
|
|
``IL_LIBRARIES``
|
|
|
|
|
The name of the IL library. These include the full path to
|
|
|
|
|
the core DevIL library. This one has to be linked into the
|
|
|
|
|
application.
|
|
|
|
|
|
|
|
|
|
``ILU_LIBRARIES``
|
|
|
|
|
The name of the ILU library. Again, the full path. This
|
|
|
|
|
library is for filters and effects, not actual loading. It
|
|
|
|
|
doesn't have to be linked if the functionality it provides
|
|
|
|
|
is not used.
|
|
|
|
|
|
|
|
|
|
``ILUT_LIBRARIES``
|
|
|
|
|
The name of the ILUT library. Full path. This part of the
|
|
|
|
|
library interfaces with OpenGL. It is not strictly needed
|
|
|
|
|
in applications.
|
|
|
|
|
|
|
|
|
|
``IL_INCLUDE_DIR``
|
|
|
|
|
where to find the il.h, ilu.h and ilut.h files.
|
|
|
|
|
|
|
|
|
|
``DevIL_FOUND``
|
|
|
|
|
This is set to TRUE if all the above variables were set.
|
|
|
|
|
This will be set to false if ILU or ILUT are not found,
|
|
|
|
|
even if they are not needed. In most systems, if one
|
|
|
|
|
library is found all the others are as well. That's the
|
|
|
|
|
way the DevIL developers release it.
|
|
|
|
|
|
|
|
|
|
``DevIL_ILUT_FOUND``
|
|
|
|
|
.. versionadded:: 3.21
|
|
|
|
|
|
|
|
|
|
This is set to TRUE if the ILUT library is found.
