Brad King c83a834d29 try_compile: Allow only languages loaded in caller (#11469)
During a try_compile cmGlobalGenerator::EnableLanguage uses results from
the outer project.  Reject attempts to enable languages in the test
project that are not "ready" in the outer project.  Mark a language as
"ready" when all its information has been loaded and we are ready to
generate build rules.

This also avoids infinite recursion introduced by commit 295b5b60 (Honor
CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile, 2010-06-29) for projects
that set CMAKE_USER_MAKE_RULES_OVERRIDE to a file that uses try_compile.
The file is loaded along with the information for a given langauge so
the language is not yet "ready".

Teach the ArgumentExpansion test to expect flattened lists as has always
been the case in the CMake language.  Now that the test should pass
enable the failure regex even when CMAKE_STRICT is not on.  Replace the
reference to the old ArgumentExpansion test behavior in the workaround
comment in cmMakefile::TryCompile with a full inline explanation.

Alex Neundorf db44848f44 Prefer files from CMAKE_ROOT when including from CMAKE_ROOT
This patch makes include() and find_package() prefer cmake files
located in CMAKE_ROOT over those in CMAKE_MODULE_PATH.
This makes sure that the including file gets that file included
which it expects, i.e. the one from cmake with which it was tested.
It only changes behaviour when such an included file exists both
in CMAKE_MODULE_PATH and in CMAKE_ROOT.
This comes together with a new policy CMP0017, with default
behaviour it behaves as it always did, but warns.
With NEW behaviour it includes the file from CMAKE_ROOT
instead from CMAKE_MODULE_PATH. This fixes (if CMP0017 is set)
building KDE 4.5 with cmake >= 2.8.3.
Also a basic test for this policy in included.

Brad King 85c0a69a92 Cygwin: Do not define 'WIN32' (#10122)
One of Cygwin's goals is to build projects using the POSIX API with no
Windows awareness.  Many CMake-built projects have been written to test
for UNIX and WIN32 but not CYGWIN.  The preferred behavior under Cygwin
in such projects is to take the UNIX path but not the WIN32 path.

Unfortunately this change is BACKWARDS INCOMPATIBLE for Cygwin-aware
CMake projects!  Some projects that previously built under Cygwin and
are Cygwin-aware when they test for WIN32 may now behave differently.
Eventually these projects will need to be updated, but to help users
build them in the meantime we print a warning about the change in
behavior.  Furthermore, one may set CMAKE_LEGACY_CYGWIN_WIN32 to request
old behavior during the transition.

Normally we avoid backwards incompatible changes, but we make an
exception in this case for a few reasons:

(1) This behavior is preferred by Cygwin's design goals.

(2) A warning provides a clear path forward for everyone who may see
incompatible behavior, and CMAKE_LEGACY_CYGWIN_WIN32 provides a
compatibility option.  The warning and compatibility option both
disappear when the minimum required version of CMake in a project is
sufficiently new, so this issue will simply go away over time as
projects are updated to account for the change.

(3) The fixes required to update projects are fairly insignificant.
Furthermore, the Cygwin distribution has no releases itself so project
versions that predate said fixes tend to be difficult to build anyway.

(4) This change enables many CMake-built projects that did not
previously build under Cygwin to work out-of-the-box.  From bug #10122:

  "I have built over 120 different source packages with (my patched)
   CMake, including most of KDE4, and have found that NOT defining
   WIN32 on Cygwin is much more accurate." -- Yaakov Selkowitz

A fully compatible change would require patches on top of these project
releases for Cygwin even though they otherwise need not be aware of it.

(5) Yaakov has been maintaining a fork of CMake with this change for the
Cygwin Ports distribution.  It works well in practice.  By accepting the
change in upstream CMake we avoid confusion between the versions.

CMake itself builds without WIN32 defined on Cygwin.  Simply disable
CMAKE_LEGACY_CYGWIN_WIN32 explicitly in our own CMakeLists.txt file.

Brad King 0621362668 Fix dependency tracing of INSTALL and PACKAGE (#11598)
Commit e01cce28 (Allow add_dependencies() on imported targets,
2010-11-19) started using cmMakefile::FindTargetToUse to follow
dependencies, including those of GLOBAL_TARGETs like INSTALL and
PACKAGE.  Since global targets exist in every directory, dependencies
between them must be traced within each directory too.

Teach FindTargetToUse to check the current directory before checking
globally.  For global targets this will find the local copy.  For for
normal targets this will be a no-op because they are globally unique.
