FindLibGpgError
---------------
Try to find the Libgpg-error library.
This will define the following variables:
``LibGpgError_FOUND``
True if (the requested version of) Libgpg-error was found
``LibGpgError_VERSION``
The version of the Libgpg-error library which was found
``LibGpgError_LIBRARIES``
Libraries you need to link when using Libgpg-error This can be passed to
target_link_libraries() instead of the ``LibGpgError::LibGpgError`` target.
``LibGpgError_INCLUDE_DIRS``
Include directories needed to use Libgpg-error This should be passed to
target_include_directories() if the target is not used for linking.
``LibGpgError_DEFINITIONS``
Compile definitions to use when compiling code that uses Libgpg-error
This should be passed to target_compile_options() if the target is not
used for linking.
If ``LibGpgError_FOUND`` is TRUE, it will also define the following imported target:
``LibGpgError::LibGpgError``
The Libgpg-error library
