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

# - Try to find the OpenSSL encryption library
# Once done this will define
#
# OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL
#
# Read-Only variables:
# OPENSSL_FOUND - system has the OpenSSL library
# OPENSSL_INCLUDE_DIR - the OpenSSL include directory
# OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
# OPENSSL_VERSION - This is set to $major.$minor.$revision$path (eg. 0.9.8s)
