d90be200 Fortran: Add support for GNU >= 4.9 compressed modules (#14975)

c491cb1e Fix some generator crashes on undefined CMAKE_BUILD_TYPE

7abd5747 cmake: Add '-E env' command-line tool

Extend the cmake command-line interface to support

 cmake -E env [--unset=NAME]... [NAME=VALUE]... COMMAND [ARG]...

This will be useful to run processes with modified environments
without using a shell or a full "cmake -P" script to wrap it.

Extend the RunCMake.CommandLine test to cover success and failure cases.

15a19c31 InstallRequiredSystemLibraries: Allow repeat use per-config

Also add an 'include' path suffix that may appear after the value of
some of the environment variables.

From the GCC 4.9 release notes for Fortran:

 https://gcc.gnu.org/gcc-4.9/changes.html
 "Module files: The version of the module files (.mod) has been
  incremented; additionally, module files are now compressed."

Teach cmDependsFortran::ModulesDiffer to look for the gzip magic numbers
at the beginning of the module file.  If found, assume the module was
produced by gfortran >= 4.9.  The modules do not appear to contain the
date as earlier versions did so we can compare the content directly
and do not actually need to decompress.

Since commit 84fdc992 (stringapi: Pass configuration names as strings,
2014-02-09), it is not safe to use GetDefinition("CMAKE_BUILD_TYPE")
without checking the return value.  Use GetSafeDefinition instead so
that a missing definition is treated as an empty string like code paths
did prior to the above commit.

With MSVC, isspace() will assert with non-ascii characters.

This allows disambiguation of identifiers in Qt Assistant and Creator.

This is necessary in order for the QHelpEngineCore::linksForIdentifier API
to work.

 http://doc-snapshot.qt-project.org/qt5-5.3/qhelpenginecore.html#linksForIdentifier

That API is used by QtCreator to enable contextual links to help files.

58cc3c22 Fix ctest to allow valgrind to show up in the path name of a memcheck tool.

To be able to include InstallRequiredSystemLibraries more than once
(e.g. to get the Debug and Release libraries separately), clear the
internal library list for non-matching configuration.

de7c2882 cmake,ccmake: Produce shorter output on no arguments (#14973)

It may happen that CMake include is an explicit dependency for some command,
while all CMake includes are set phony in WriteTargetRebuildManifest, this may
lead to duplicate phony generate rules which causes ninja warnings.

We need to remove implicit CMake includes in WriteUnknownExplicitDependencies.

This fixes FindCUDA ninja warnings.

c746b00e Encoding:  Change to only set LC_CTYPE to fix encoding issues with libarchive.

For testing purposes CMake creates dummy memory checkers.  The dummy checkers
are in the CMake build tree. Before this change when the path contained the
string valgrind, such as CMake-valgrind, all the checkers were thought to
be valgrind, and this caused tests to fail.

Enable the alignment features for Clang.
