Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code 
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
 '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
egrep -z -v '^(Modules/CPack\..*\.in)' |
xargs -0 sed -i 's/ \+$//'

# - Find Perl libraries
# This module finds if PERL is installed and determines where the include files
# and libraries are. It also determines what the name of the library is. This
# code sets the following variables:
#
# PERLLIBS_FOUND = True if perl.h & libperl were found
# PERL_INCLUDE_PATH = path to where perl.h is found
# PERL_LIBRARY = path to libperl
# PERL_EXECUTABLE = full path to the perl binary
#
# The minimum required version of Perl can be specified using the
# standard syntax, e.g. FIND_PACKAGE(PerlLibs 6.0)
#
# The following variables are also available if needed
# (introduced after CMake 2.6.4)
#
# PERL_SITESEARCH = path to the sitesearch install dir
# PERL_SITELIB = path to the sitelib install directory
# PERL_VENDORARCH = path to the vendor arch install directory
# PERL_VENDORLIB = path to the vendor lib install directory
# PERL_ARCHLIB = path to the arch lib install directory
# PERL_PRIVLIB = path to the priv lib install directory
# PERL_EXTRA_C_FLAGS = Compilation flags used to build perl
