FindSelfPackers
---------------
Finds `UPX <https://upx.github.io/>`_, the Ultimate Packer for eXecutables:
.. code-block:: cmake
find_package(SelfPackers [...])
This module searches for executable packers-tools that compress executables or
shared libraries into on-the-fly, self-extracting versions. It currently
supports ``UPX``.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``SelfPackers_FOUND``
.. versionadded:: 4.2
Boolean indicating whether packer tools were found.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``SELF_PACKER_FOR_EXECUTABLE``
Path to the executable packer for compressing executables.
``SELF_PACKER_FOR_SHARED_LIB``
Path to the executable packer for compressing shared libraries.
``SELF_PACKER_FOR_EXECUTABLE_FLAGS``
Command-line options to use when compressing executables.
``SELF_PACKER_FOR_SHARED_LIB_FLAGS``
Command-line options to use when compressing shared libraries.
Examples
^^^^^^^^
