# 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 <[email protected]>
# Refined and expanded by Daniel Richard G. <[email protected]>
# 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

# 2012-09-08 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

# 2015-04-24 PH added support for PCRE2_DEBUG
# 2015-07-16 PH updated for new pcre2_find_bracket source module
