Brad King ff386d1121 Modules: Make imported targets fall back to Release
Find modules only detect Debug and Release configurations.  All other
configurations will fall back to the configuration listed as the first
entry in `IMPORTED_CONFIGURATIONS`.  Switch the order so that `Release`
is listed first, as this is a better fallback than `Debug` for the
`RelWithDebInfo` and `MinSizeRel` configurations.  See issue #16091.

This approach is recommended by documentation in `cmake-developer(7)`
added by commit v3.2.0-rc1~286^2~1 (Help: Document IMPORTED_CONFIGURATIONS
target property for Find modules, 2014-12-04).

#.rst:
# FindXercesC
# -----------
#
# Find the Apache Xerces-C++ validating XML parser headers and libraries.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` targets:
#
# ``XercesC::XercesC``
# The Xerces-C++ ``xerces-c`` library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``XercesC_FOUND``
# true if the Xerces headers and libraries were found
# ``XercesC_VERSION``
# Xerces release version
# ``XercesC_INCLUDE_DIRS``
# the directory containing the Xerces headers
# ``XercesC_LIBRARIES``
# Xerces libraries to be linked
#
# Cache variables
# ^^^^^^^^^^^^^^^
#
# The following cache variables may also be set:
#
# ``XercesC_INCLUDE_DIR``
# the directory containing the Xerces headers
# ``XercesC_LIBRARY``
# the Xerces library
