Ben Boeckel bc38565863 EVIS: Reimplement using custom parsing code
Introduce a new implementation of ExpandVariablesInString and select
between the old and new implementations based on policy CMP0053.
Instead of cmCommandArgumentParserHelper, use a custom parser with our
own stack.  This is much faster and works well for our simple grammar.

The new behavior of CMP0053 should expand @VAR@ syntax only in certain
contexts.  All existing EVIS callers use "replaceAt == true" so
hard-code our call to the old implementation.  Update the signature to
default to "replaceAt == false" and pass "replaceAt == true" explicitly
in the call sites for configure_file and string(CONFIGURE).

Testing the configure (no generate) step with ParaView shows ~20%
performance improvement.

In terms of complete configure/generate steps, further testing with
ParaView shows a 20% performance improvement over 2.8.12.2 with Unix
Makefiles and minimal with Ninja. Ninja is less because it generate step
is the expensive part (future work will address this) by a long shot and
these changes help the configure step for the most part.

Ben Boeckel 25102efc1d EVIS: Add policy CMP0053
This policy switches between the old EVIS parser and the new, faster
parser.

There are no versions of /MANIFESTUAC:NO where addition values are
appended.  Remove both of the MANIFESTUAC:NO entries from our flag
tables and replace them with one which would set EnableUAC to false and
immediately stop processing the /MANIFESTUAC:NO option.

Drop the icon file extension.  This fixes the desktop file validation
message:

 name with an extension, but there should be no extension as described in
 the Icon Theme Specification if the value is not an absolute path

Mikołaj Siedlarek 1bed75a590 OS X: Use -iframework for system framework directories
Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.

Stephen Kelly 1df2116bfa Features: Decay language flag if requested is not available.
Use the highest standard compile flags available if requested language
version is too new.

This supports use-cases like

 set(CMAKE_CXX_STANDARD 14)

 # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
 # or equivalent flag
 add_executable(main main.cpp)

This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.

Stephen Kelly d648c4766f cmTarget: Don't assert on object libraries for configure-time location.
Commit b8af2011 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13) refactored a GetObjectLibrariesCMP0026
method out of GetLanguages.  In flight, a conditional use of a target
if available was changed to an assert-available.

This code is only used to read the LOCATION property at configure
time, when the link information is incomplete, and not all targets
are defined, so the assert is inappropriate, even though it can lead
to incorrect information being generated.  CMP0026 warns about the
potentially incorrect information anyway.
