# CMakeLists.txt
#
# This file enables PCRE2 to be built with the CMake configuration and build
# tool. Download CMake in source or binary form from http://www.cmake.org/
# Converted to support PCRE2 from the original PCRE file, August 2014.
#
# 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 added test for inttypes.h
# 2011-08-01 PH added PCREGREP_BUFSIZE
# 2011-08-22 PH added PCRE_SUPPORT_JIT
# 2011-09-06 PH modified WIN32 ADD_TEST line as suggested by Sergey Cherepanov
# 2011-09-06 PH added PCRE_SUPPORT_PCREGREP_JIT
# 2011-10-04 Sheri added support for including coff data in windows shared libraries
#            compiled with MINGW if pcre.rc and/or pcreposix.rc are placed in
#            the source dir by the user prior to building
# 2011-10-04 Sheri changed various add_test's to use exes' location built instead
#            of DEBUG location only (likely only matters in MSVC)
# 2011-10-04 Sheri added scripts to provide needed variables to RunTest and
#            RunGrepTest (used for UNIX and Msys)
# 2011-10-04 Sheri added scripts to provide needed variables and to execute
#            RunTest.bat in Win32 (for effortless testing with "make test")
# 2011-10-04 Sheri Increased minimum required cmake version
# 2012-01-06 PH removed pcre_info.c and added pcre_string_utils.c
# 2012-01-10 Zoltan Herczeg added libpcre16 support
# 2012-01-13 Stephen Kelly added out of source build support
# 2012-01-17 PH applied Stephen Kelly's patch to parse the version data out
#            of the configure.ac file
# 2012-02-26 PH added support for libedit
# 2012-09-06 PH added support for PCRE_EBCDIC_NL25
# 2012-09-08 ChPe added PCRE32 support
# 2012-10-23 PH added support for VALGRIND and GCOV
# 2012-12-08 PH added patch from Daniel Richard G to quash some MSVC warnings
# 2013-07-01 PH realized that the "support" for GCOV was a total nonsense and
#            so it has been removed.
# 2013-10-08 PH got rid of the "source" command, which is a bash-ism (use ".")
# 2013-11-05 PH added support for PARENS_NEST_LIMIT
# 2014-08-29 PH converted the file for PCRE2 (which has no C++).
# 2015-04-24 PH added support for PCRE2_DEBUG
# 2015-07-16 PH updated for new pcre2_find_bracket source module
# 2015-08-24 PH correct C_FLAGS setting (patch from Roy Ivy III)

# 2016-03-01 PH applied Chris Wilson's patch for MSVC static
# 2016-06-24 PH applied Chris Wilson's second patch, putting the first under
#            a new option instead of being unconditional.
# 2016-10-05 PH fixed a typo (PCRE should be PCRE2) in above patch
#            fix by David Gaussmann

# 2018-06-27 PH added Daniel's patch to increase the stack for MSVC
# 2018-11-14 PH removed unnecessary checks for stdint.h and inttypes.h
# 2018-11-16 PH added PCRE2GREP_SUPPORT_CALLOUT_FORK support and tidied

#            build in one go.
