pcre/LICENCE

-PCRE LICENCE
-------------
-
-PCRE is a library of functions to support regular expressions whose syntax
-and semantics are as close as possible to those of the Perl 5 language.
-
-Release 8 of PCRE is distributed under the terms of the "BSD" licence, as
-specified below. The documentation for PCRE, supplied in the "doc"
-directory, is distributed under the same terms as the software itself. The data
-in the testdata directory is not copyrighted and is in the public domain.
-
-The basic library functions are written in C and are freestanding. Also
-included in the distribution is a set of C++ wrapper functions, and a
-just-in-time compiler that can be used to optimize pattern matching. These
-are both optional features that can be omitted when the library is built.

-# 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.
