FindBZip2
---------
Try to find BZip2
IMPORTED Targets
^^^^^^^^^^^^^^^^
This module defines :prop_tgt:`IMPORTED` target ``BZip2::BZip2``, if
BZip2 has been found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``BZIP2_FOUND``
system has BZip2
``BZIP2_INCLUDE_DIRS``
the BZip2 include directories
``BZIP2_LIBRARIES``
Link these to use BZip2
``BZIP2_NEED_PREFIX``
this is set if the functions are prefixed with ``BZ2_``
``BZIP2_VERSION_STRING``
the version of BZip2 found
Cache variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``BZIP2_INCLUDE_DIR``
the BZip2 include directory
