When the CMAKE_GENERATOR option is given to ExternalProject_Add, look
also for option CMAKE_GENERATOR_TOOLSET to select the value of the cmake
"-T" command-line flag. When no CMAKE_GENERATOR option is given
explicitly then use the current project's CMAKE_GENERATOR_TOOLSET (since
we already use its CMAKE_GENERATOR).
Teach CMakeParseImplicitLinkInfo to convert implicit link library full
paths to a canonical form. This makes them more reproducible in case
different language compiler front-ends add the same library by different
paths e.g. ".../libA.a" and "...//libA.a".
Add a case to the CMake.ImplicitLinkInfo test to cover removal of extra
slashes from both library and directory paths.

Each data file to be created in the build tree corresponds one-to-one with
a raw file or content link in the source tree. Use the MAIN_DEPENDENCY of
add_custom_command to attach the build rule to the source tree file. This
looks much nicer in the IDE project file browser and avoids ".rule" files.
Use private global variables _ExternalData_REGEX_(ALGO|EXT) to match the
possible hash algorithm names and extensions in regular expressions.
Use "file(<algo>)" instead of "cmake -E md5sum" to compute hashes
without a child process and to support more hash algorithms.
Use a trailing slash to reference a directory. Require that a list
of associated files be specified to select from within the directory.
One may simply use DATA{Dir/,REGEX:.*} to reference all files but
get a directory passed on the command line.
Refactor use of the ExternalData_SERIES_MATCH value to avoid assuming
that it has no ()-groups that interfere with group indexing.
Extend the Module.ExternalData test to cover this case.
Automatic series recognition can generate false positives too easily
when the default series configuration is flexible enough to handle
common cases. Avoid false positives by requiring an explicit syntax to
activate series recognition. Choose the syntax DATA{<name>,:} to be
short, simple, and look like a vertical ellipsis.
This allows us to improve the default series match configuration. Allow
series references to contain one of the numbered file names. Allow '-'
as a separator in addition to '.' and '_'. Document what the default
configuration matches. Also provide more options to configure series
<name> parsing.
Before this, when creating GTK2_LIBRARIES, FindGTK2 added the GTK
dependencies in wrong order into GTK2_LIBRARIES. With dynamic libraries
this is not a major problem, but when linking to static gtk libraries,
the linker outputs a lot of undefined symbols. Reorder the calls that
append libraries to GTK2_LIBRARIES to respect dependency order.
The configure_package_config()_file() macro will now use
absolute paths for the PATH_VARS if the Config.cmake file
will be installed into /lib(64) or /usr/lib(64), since due to
the usr-move filesystem changes Config.cmake files installed
there may be found via two paths (once per symlink via
/lib(64) and once via /usr/lib ), and in this case
relative paths break.

Take files we previously distributed in ITK 4.3.1:
CMake/ExternalData.cmake
CMake/ExternalData_config.cmake.in
and add them for distribution in upstream CMake. Update the copyright
notice block format to follow CMake conventions.
The ExternalProject_Add DEPENDS option adds two types of dependencies.
It adds a target-level build order dependency between the external
project target and the named targets. It also adds a file-level
dependency on the "done" stamp file of the named external project
targets. Targets not created by ExternalProject_Add have no such stamp
file and no _EP_STAMP_DIR property. Prior to commit d14c0243 (Refactor
repeated code into function, 2012-04-26) we unconditionally accepted an
empty stamp dir and generated a dependency on a non-existent file.
After that commit we generate an error that no stamp dir is set.
Skip the file-level dependency when the named dependency is not an
external project target in order to allow this use case. Teach the
ExternalProject test to cover the case.

cc676c3 OS X: Detect implicit linker framework search paths
2dd67c7 OS X: Detect implicit link directories on modern toolchains
ba58d0c OS X: Link with all framework search paths, not just the last
This means for example, that consumers can use:
target_link_libraries(foo ${QT_QTGUI_LIBRARIES})
instead of also needing to specify all 'public' dependencies:
target_link_libraries(foo ${QT_QTGUI_LIBRARIES} ${QT_QTCORE_LIBRARIES} )
when using the IMPORTED targets. Also populate the
IMPORTED_LINK_DEPENDENT_LIBRARIES property so CMake can help the linker
find shared library dependencies.
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions. Instead we should automatically detect the framework
directories for the active toolchain.
The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories. It displays a block such as:
Framework search paths:
/...
Parse this block to extract the list of framework directories.
Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers. Always treat the paths
<sdk>/Library/Frameworks
<sdk>/System/Library/Frameworks
<sdk>/Network/Library/Frameworks # Older OS X only
/System/Library/Frameworks
as implicit. Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.
We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary. Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld". Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.
Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:
Library search paths:
/...
Parse this block to extract the implicit link directories.
While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22). Discard
the non-system link directories added by Xcode. Discard all detected
implicit libraries in the multi-architecture case but keep the
directories. The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.
