Stephen Kelly e0890d03a4 Features: Extend concept to C language.
Add properties and variables corresponding to CXX equivalents.

Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.

Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.

Stephen Kelly 62a4a67dc5 Add the WriteCompilerDetectionHeader module.
Provide a function to write a portable header to detect compiler
features.  Generate a preprocessor #error for unknown compilers
and compiler versions whose features are not yet recorded.  This
error condition might be relaxed in the future, but for now it
is useful for verification of expectations.

Daniele E. Domenichelli be8ae96098 Allow the Package Registry to be disabled (#14849)
When a project is packaged for redistribution the local package
registries should not be updated or consulted.  They are for developers.

Add variables to disable use of package registries globally:

* CMAKE_EXPORT_NO_PACKAGE_REGISTRY that disables the export(PACKAGE)
  command
* CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY that disables the User Package
  Registry in all the find_package calls.
* CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY that disables the
  System Package Registry in all the find_package calls.

Update documentation and unit tests.

Brad King 911cc9a39e cmTarget: Evaluate CMP0026 and CMP0051 in calling context
These policies should be checked at the call site that tries to access
the LOCATION or SOURCES property, not the directory scope containing the
target.  Thread the caller context through cmTarget::GetProperty to use
for checking the policy setting and emitting a diagnostic with proper
backtrace.

Extend the RunCMake.CMP0026 and RunCMake.CMP0051 tests with
cross-directory cases.

Stephen Kelly f5bf9d4311 Tests: Make CompileFeature tests use highest standard known.

file compiles, but it is documented as available first in GNU 4.8.

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.

Rolf Eike Beer b0f277db38 HP aCC: record compiler flag for Ansi C++98 support for version 3.80 onwards
Old versions of aCC need a special compiler flag to get full C++98 template
support as e.g. CMake itself or the Complex and ComplexOneConfig tests need.
The same versions need a special flag to get a proper C++ library, too.

Brad King ccd29b9af8 ExternalData: Warn on missing file instead of failing
When the primary source tree path named by a DATA{} reference does not
exist, produce an AUTHOR_WARNING instead of a FATAL_ERROR.  This is
useful when writing a new DATA{} reference to a test reference output
that has not been created yet.  This way the developer can run the test,
manually verify the output, and then copy it into place to provide the
reference and eliminate the warning.

If the named source tree path is expected to be a file but exists as a
directory, we still need to produce a FATAL_ERROR.
