# tool. Download CMake in source or binary form from http://www.cmake.org/
#
# Original listfile by Christian Ehrlicher <Ch.Ehrlicher@gmx.de>
# Refined and expanded by Daniel Richard G. <skunk@iSKUNK.ORG>
# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered
# 2007-09-19 Adjusted by PH to retain previous default settings
# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
#            (b) Ensure pcretest and pcregrep link with the local library,
#                not a previously-installed one.
#            (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
#                PCRE_SUPPORT_LIBBZ2.
# 2008-01-20 Brought up to date to include several new features by Christian
#            Ehrlicher.
# 2008-01-22 Sheri added options for backward compatibility of library names
#            when building with minGW:
#            if "ON", NON_STANDARD_LIB_PREFIX causes shared libraries to
#            be built without "lib" as prefix. (The libraries will be named
#            pcre.dll, pcreposix.dll and pcrecpp.dll).
#            if "ON", NON_STANDARD_LIB_SUFFIX causes shared libraries to
#            be built with suffix of "-0.dll". (The libraries will be named
#            libpcre-0.dll, libpcreposix-0.dll and libpcrecpp-0.dll - same names
#            built by default with Configure and Make.
# 2008-01-23 PH removed the automatic build of pcredemo.
# 2008-04-22 PH modified READLINE support so it finds NCURSES when needed.
# 2008-07-03 PH updated for revised UCP property support (change of files)
# 2009-03-23 PH applied Steven Van Ingelgem's patch to change the name
#            CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE
#            is included within another project.
# 2009-03-23 PH applied a modified version of Steven Van Ingelgem's patches to
#            add options to stop the building of pcregrep and the tests, and
#            to disable the final configuration report.
# 2009-04-11 PH applied Christian Ehrlicher's patch to show compiler flags that
#            are set by specifying a release type.
# 2010-01-02 PH added test for stdint.h
# 2010-03-02 PH addes test for inttypes.h
