Stephen Kelly 0dfe395e3c Features: Add COMPILE_FEATURES generator expression.
Allow setting build properties based on the features available
for a target.  The availability of features is determined at
generate-time by evaluating the link implementation.

Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.

Brad King e4114ee9e9 Tests/BuildDepends: Make 3-second delay more robust
Use "cmake -E sleep 3" instead of execute_process with a TIMEOUT of 3.
This avoids using a busy loop or depending on a timeout to kill it.

Brad King 42bbf1307a CMP0022: Fix link language propagation in NEW behavior
The languages used in compiling STATIC libraries need to be propagated
to dependents regardless of the settings of INTERFACE_LINK_LIBRARIES or
CMP0022.  They are independent of the libraries in the link interface.

Prior to commit v2.8.12~192^2~2 (Introduce the INTERFACE_LINK_LIBRARIES
property, 2013-06-04) the cmTarget::ComputeLinkInterface code path for
"explicitLibraries" could never be taken for STATIC libraries, so the
logic to propagate languages existed only in the non-explicitLibraries
code path.  After that commit, INTERFACE_LINK_LIBRARIES could be set for
STATIC libraries to cause the "explicitLibraries" code path to be taken.
The commit also left the old non-explicitLibraries code path conditional
on CMP0022 not being set to NEW.  Thus link language propagation was
left missing from two cases by that commit.

The explicitLibraries code path was fixed to propagate languages by
commit v2.8.12~149^2~1 (cmTarget: Fix iface libraries and languages for
static libraries, 2013-07-26).  However, the non-explicitLibraries case
was never taught to propagate languages when CMP0022 is set to NEW.  Fix
that now.  Factor the logic to propagate link languages out of the link
interface libraries conditions so that it always occurs.  Update
Tests/Fortran to set CMP0022 to NEW to test this case (because the test
passes only if link language propagation works).

Joseph Snyder 9ad07fbeb8 CTest: Fix MUMPS coverage parsing and test
Fix the MUMPS coverage parser:

* Account for tabs after entry points

* Stop double incrementing lines that have explicit calls to the 0 line

* If a line has been previously marked as non executable, but then
  contains a count, increment it an extra one to push it back into
  the executable code set.

Add a custom routine and corresponding coverage files in the test case.
This file is smaller and has cmcov/mcov files that have data for only
that routine.

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.

Provide a function to write a portable header to detect compiler

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.

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.
