Kitware Robot 9db3116226 Remove CMake-language block-end command arguments 
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

# - 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
