This commit updates PCRE2 to 10.34, and we no longer include what's in their tarball as-is. I've yanked out a lot of uneccessary stuff for the sake of the size of our codebase. original pcre2-10.34 dir: 11.5MB pcre2 dir in this commit: 1.6MB * Remove documentation, makefiles, test suites, etc. LICENSE remains. * Disable building tests when configuring PCRE2 * Yard out JIT support: delete src/jit, src/pcre2_jit_*.c, and code doing stuff to code->executable_jit that needs a jit header (it was already NULL because we've always built with JIT disabled). * Remove most .c and .h files not needed to compile: pcre2grep code, pcre2test code, dftables.c, pcre2_printint.c, pcre2_fuzzsupport.c ... * Remove FindBZip2, FindZLIB, FindReadline, FindEditline. These were used only by pcre2grep and made CMake's report misleading with regard to optional packages being used. * Remove configure.ac except for version number and date which CMake checks Next time we update PCRE2, refer to this commit message as well as a diff between pcre2-10.34.tar.gz and ./pcre2-10.34/. Or better yet, cease including pcre2.

# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )
|
|
# This macro is intended to be used in FindXXX.cmake modules files.
|
|
# It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
|
|
# it also sets the <UPPERCASED_NAME>_FOUND variable.
|
|
# The package is found if all variables listed are TRUE.
|
|
# Example:
|
|
#
|
|
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
|
|
#
|
|
# LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
|
|
# LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
|
|
# If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
|
|
# independent whether QUIET was used or not.
|
|
# If it is found, the location is reported using the VAR1 argument, so
|
|
# here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
|
|
# If the second argument is DEFAULT_MSG, the message in the failure case will
|
|
# be "Could NOT find LibXml2", if you don't like this message you can specify
|
|
# your own custom failure message there.
