FindEXPAT
---------
Find the native Expat headers and library.
Expat is a stream-oriented XML parser library written in C.
Imported Targets
^^^^^^^^^^^^^^^^
.. versionadded:: 3.10
This module defines the following :prop_tgt:`IMPORTED` targets:
``EXPAT::EXPAT``
The Expat ``expat`` library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
``EXPAT_INCLUDE_DIRS``
where to find expat.h, etc.
``EXPAT_LIBRARIES``
the libraries to link against to use Expat.
``EXPAT_FOUND``
true if the Expat headers and libraries were found.
