Rolf Eike Beer 745b56f58c Find*.cmake: drop the comments before including FPHSA
No need to explain this over and over again.  While at it, do some other
minor cleanups to whitespace and comments (i.e. delete them).

# FindTIFF
# --------
#
# Find the TIFF library (libtiff).
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` targets:
#
# ``TIFF::TIFF``
# The TIFF library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``TIFF_FOUND``
# true if the TIFF headers and libraries were found
# ``TIFF_INCLUDE_DIR``
# the directory containing the TIFF headers
# ``TIFF_INCLUDE_DIRS``
# the directory containing the TIFF headers
# ``TIFF_LIBRARIES``
# TIFF libraries to be linked
#
# Cache variables
# ^^^^^^^^^^^^^^^
#
# The following cache variables may also be set:
#
# ``TIFF_INCLUDE_DIR``
# the directory containing the TIFF headers
# ``TIFF_LIBRARY``
# the path to the TIFF library
