Brad King 1823ab4d76 ExternalData: Preserve escaped semicolons during argument expansion
The CMake language implicitly flattens lists so a ";" in a list element
must be escaped with a backslash.  List expansion removes backslashes
escaping semicolons to leave raw semicolons in the values.  Teach
ExternalData_Add_Test and ExternalData_Expand_Arguments to re-escape
semicolons found in list elements so the resulting argument lists work
as if constructed directly by the set() command.

For example:

  ExternalData_Add_Test(Data NAME test1 COMMAND ... "a\\;b")
  ExternalData_Expand_Arguments(Data args2 "c\\;d")
  add_test(NAME test2 COMMAND ... ${args2})

should be equivalent to

  set(args1 "a\\;b")
  add_test(NAME test1 COMMAND ... ${args1})
  set(args2 "c\\;d")
  add_test(NAME test2 COMMAND ... ${args2})

which is equivalent to

  add_test(NAME test1 COMMAND ... "a;b")
  add_test(NAME test2 COMMAND ... "c;d")

Note that it is not possible to make ExternalData_Add_Test act exactly
like add_test when quoted arguments contain semicolons because the CMake
language flattens lists when constructing function ARGN values.  This
re-escape approach at least allows test arguments to have semicolons.

While at it, teach ExternalData APIs to not transform "DATA{...;...}"
arguments because the contained semicolons are non-sensical.

This is CMake, the cross-platform, open-source make system.

or visit http://www.cmake.org.


Building CMake
==============


Supported Platforms
-------------------

MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX

Other UNIX-like operating systems may work too out of the box, if not
it shouldn't be a major problem to port CMake to this platform. Contact the
CMake mailing list in this case: http://www.cmake.org/mailman/listinfo/cmake


If you don't have any previous version of CMake already installed
--------------------------------------------------------------

* UNIX/Mac OSX/MinGW/MSYS/Cygwin:

You need to have a compiler and a make installed.
Run the bootstrap script you find the in the source directory of CMake.
You can use the --help option to see the supported options.
You may want to use the --prefix=<install_prefix> option to specify a custom
installation directory for CMake. You can run the bootstrap script from
within the CMake source directory or any other build directory of your
choice. Once this has finished successfully, run make and make install.
So basically it's the same as you may be used to from autotools-based
projects:

$ ./bootstrap; make; make install


* Other Windows:

You need to download and install a binary release of CMake in order to build
CMake.  You can get these releases from
http://www.cmake.org/HTML/Download.html .  Then proceed with the instructions
below.


You already have a version of CMake installed
---------------------------------------------

You can build CMake as any other project with a CMake-based build system:
run the installed CMake on the sources of this CMake with your preferred
options and generators. Then build it and install it.
For instructions how to do this, see http://www.cmake.org/HTML/RunningCMake.html
