-^^^^^^^^^^^^^^^^
-
-``Blosc::blosc``
-  This module defines IMPORTED target Blosc::Blosc, if Blosc has been found.
-
-Result Variables
-^^^^^^^^^^^^^^^^
-
-This will define the following variables:
-

-^^^^^^^^^^^^^^^
-
-The following cache variables may also be set:
-
-``Blosc_INCLUDE_DIR``
-  The directory containing ``blosc.h``.
-``Blosc_LIBRARY``
-  The path to the Blosc library.
-
-Hints

-Instead of explicitly setting the cache variables, the following variables
-may be provided to tell this module where to look.
-
-``BLOSC_ROOT``
-  Preferred installation prefix.

-Find OpenEXR include dirs and libraries
-
-Use this module by invoking find_package with the form::
-
-  find_package(OpenEXR
-    [version] [EXACT]      # Minimum or EXACT version
-    [REQUIRED]             # Fail with error if OpenEXR is not found
-    [COMPONENTS <libs>...] # OpenEXR libraries by their canonical name
-                           # e.g. "IlmImf" for "libIlmImf"
-    )
-
-IMPORTED Targets
-^^^^^^^^^^^^^^^^
-
-``OpenEXR::IlmImf``
-  The IlmImf library target.
-``OpenEXR::IlmImfUtil``
-  The IlmImfUtil library target.
-
-Result Variables
-^^^^^^^^^^^^^^^^
-
-This will define the following variables:
-
-``OpenEXR_FOUND``
-  True if the system has the OpenEXR library.
-``OpenEXR_VERSION``
-  The version of the OpenEXR library which was found.
-``OpenEXR_INCLUDE_DIRS``
-  Include directories needed to use OpenEXR.
-``OpenEXR_LIBRARIES``
-  Libraries needed to link to OpenEXR.
-``OpenEXR_LIBRARY_DIRS``
-  OpenEXR library directories.
-``OpenEXR_DEFINITIONS``
-  Definitions to use when compiling code that uses OpenEXR.
-``OpenEXR_{COMPONENT}_FOUND``
-  True if the system has the named OpenEXR component.
-
-Cache Variables
-^^^^^^^^^^^^^^^
-
-The following cache variables may also be set:
-
-``OpenEXR_INCLUDE_DIR``
-  The directory containing ``OpenEXR/config-auto.h``.
-``OpenEXR_{COMPONENT}_LIBRARY``
-  Individual component libraries for OpenEXR
-``OpenEXR_{COMPONENT}_DLL``
-  Individual component dlls for OpenEXR on Windows.
-
-Hints
-^^^^^
-
-Instead of explicitly setting the cache variables, the following variables
-may be provided to tell this module where to look.
-
-``OPENEXR_ROOT``
-  Preferred installation prefix.
-``OPENEXR_INCLUDEDIR``
-  Preferred include directory e.g. <prefix>/include
-``OPENEXR_LIBRARYDIR``
-  Preferred library directory e.g. <prefix>/lib
-``SYSTEM_LIBRARY_PATHS``
-  Paths appended to all include and lib searches.
