Extend the range of valid target names with the + sign. This character
can commonly be used for target names, such as those containing 'c++'.
Add a test but skip it for Borland and Watcom tools which do not support
the character.

When the command is invoked without an explicit build directory path we
compute it from the source directory path. When either the source or
build tree is the root of a Windows drive letter it will have a trailing
slash. Handle slashes consistently when substituting the current output
directory for the current source directory.
While at it, use cmSystemTools::IsSubDirectory instead of FindLastString
to verify that the source directory is a subdirectory.

* Clarify accepted values of <LANG> suffix in CMAKE_COMPILER_IS_GNU<LANG>.
* Clarify fact that target property GENERATOR_FILE_NAME usually cannot be
used at configure time.
* Clarify that enable_language() can only be used in global scope of
top-level project using language.
* State that enable_language(... OPTIONAL) currently doesn't work.
* Document regular expression operator precedence.
If the absolute install(EXPORT) destination for the CMAKE_INSTALL_PREFIX
used during configuration is under (/usr)?/lib(64)? then assume the
current build is for a system package installation instead of a
relocatable distribution. Generate an absolute path for _IMPORT_PREFIX
in the target exports file instead of generating code to compute the
value relative to the file location. This is necessary for
distributions implementing a move to /usr such as:
https://wiki.archlinux.org/index.php/DeveloperWiki:usrlib
"All files in the /lib directory have been moved to /usr/lib and now
/lib is a symlink to usr/lib."
The relative path computation is not reliable because the targets file
could be installed through cross-prefix a symlink and loaded without it
or vice versa.
A similar change was made for package configuration file generation by
commit d4774140 (configure_package_config_file: force absolute paths for
usr-move, 2013-01-24).
Teach the WriteGroup method return true if a group or any of its
children have source files. Have children write their output to a
temporay cmOStringStream. Add it to the real output only if not empty.
Only check a release version for the minimum required version. If NSIS
returns a CVS build version string (as when built by Macports), skip the
version check altogether and assume a sufficiently new version. Also
correctly handle the case where the version check fails and the
CPACK_TOPLEVEL_DIRECTORY option is not set.

Commit a1c4905f (Use the link information as a source of compile
definitions and includes., 2013-02-12) introduced the use of link
information as the source of target properties via the TARGET_PROPERTY
generator expression. This generator expression has a strict
interpretation of a valid target name and emits a fatal error for
invalid names.
Ensure that only targets with names valid for use with TARGET_PROPERTY
or targets which are determined by generator expressions are processed
by it. This means that at worst, invalid target names do not participate
in the transitive evaluation of properties, but the validation
generator expression can be extended where needed to resolve that.
cbf0756 Revert "Add the TARGET_DEFINED generator expression"
21a342c Remove use of TARGET_DEFINED from the target_link_libraries test.
47b8d32 Remove use of TARGET_DEFINED from the ExportImport test.
2e39d21 Remove use of TARGET_DEFINED from target_include_directories test.
Use the /STACK: flag to pass the value through flag parsing so that the
generator converts it to the StackReserveSize project file option. The
option was accidentally left out by commit 7491f529 (first pass at VS
10, 2009-06-25).

As of commit 1da75022 (Don't include generator expressions in
old-style link handling., 2012-12-23), such entries are not
included in the LinkLibraries member. Generator expressions in
LinkLibraries are not processed anyway, so port to the new way
of getting link information.
In the case of input like
foo$<1:bar>
the preGenex should be 'foo'. In that case, the search for a ';'
will not find one, and there is no preceding input to process as a
non-genex list.
Previously, the result of 'splitting' such a string would instead
be a vector containing the same string two times.
