Brad King 7d47c69365 Drop compatibility with CMake < 2.4
Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to
a value lower than 2.4, and generate an error when projects or the user
attempt to do so.  In the error suggest using a CMake 2.8.x release.

Teach cmake_minimum_required to warn about projects that do not require
at least CMake 2.4.  They are not supported by CMake >= 3.0.

Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a
reference to policy CMP0001.

Brad King 2e13c36211 OS X: Encode -F framework search flag in per-language platform variable
Compilers for languages other than C and C++ on OS X may not understand
the -F framework search flag.  Create a new platform information
variable CMAKE_<LANG>_FRAMEWORK_SEARCH_FLAG to hold the flag, and set it
for C and CXX lanugages in the Platform/Darwin module.

Stephen Kelly fe732264e9 Add the INTERFACE_LIBRARY target type.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.

The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.

An ALIAS target may be created for an INTERFACE library.

At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.

The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.

Stephen Kelly 33055c405e Generate modern-style cmake code.
The commits 9db31162 (Remove CMake-language block-end command
arguments, 2012-08-13) and 77543bde (Convert CMake-language
commands to lower case, 2012-08-13) changed most cmake code
to use lowercase commands and no parameters in termination
commands. However, those changes excluded cmake code generated
in c++ by cmake.

Make a similar style change to code generated by cmake.

Brad King 4bb6e24809 VS,Xcode: Drop incorrect legacy dependency trace (#14291)
Drop the "vsProjectFile" argument from cmTarget::TraceDependencies.  It
appears to be the modern equivalent to a hunk added in commit ba68f771
(...added new custom command support, 2003-06-03):

 +  name = libName;
 +  name += ".dsp.cmake";
 +  srcFilesToProcess.push(name);

but was broken by refactoring at some point.  The current behavior tries
to trace dependencies on a source file named the same as a target, which
makes no sense.  Furthermore, in code of the form

 add_executable(foo foo.c)
 add_custom_command(OUTPUT "${somewhere}/foo" ... DEPENDS foo)

the "vsProjectFile" value "foo" matches source "${somewhere}/foo.rule"
generated to hold the custom command and causes the command to be added
to the "foo" target incorrectly.

Simply drop the incorrect source file trace and supporting logic.

Brad King d221eac812 Refactor target COMPILE_OPTIONS and COMPILE_FLAGS handling
Replace the cmLocalGenerator GetCompileOptions method with an
AddCompileOptions method since all call sites of the former simply
append the result to a flags string anyway.

Add a "lang" argument to AddCompileOptions and move the
CMAKE_<LANG>_FLAGS_REGEX filter into it.  Move the call sites in each
generator to a location that has both the language and configuration
available.  In the Makefile generator this also moves the flags from
build.make to flags.make where they belong.

Stephen Kelly 2d9ec1dadf Add compiler target compile options.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like

 set(triple arm-linux-gnueabihf)
 set(CMAKE_C_COMPILER "/usr/bin/clang")
 set(CMAKE_C_COMPILER_TARGET ${triple})
 set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
 set(CMAKE_CXX_COMPILER_TARGET ${triple})

or

 set(arch gcc_ntoarmv7le)
 set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
 set(CMAKE_C_COMPILER_TARGET ${arch})
 set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
 set(CMAKE_CXX_COMPILER_TARGET ${arch})

Both clang and qcc are inherently cross compiler( driver)s.

Stephen Kelly de4da665d3 Use --sysroot when cross compiling.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.

The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.

Stephen Kelly 753b905ec8 Automoc: append implicit includes after user-specified dirs
The commit d2536579 (Automoc: fix regression #13667, broken build in
phonon, 2012-11-19) changed Automoc to try to re-add the Qt header dir
if it was stripped out as an implicit include from the moc command
line. When invoking a compiler, those directories are stripped out
because they are built-in, but for moc, there are no built-in directories.

The follow-up commit acc22400 (Automoc: get include dirs without
stripping implicit include dirs off, 2012-12-07) went further by not
removing the implicit include dirs, if they were specified specifically
by the user.

This had the remaining problem that the implicit include dirs appeared
in a different order of precedence for moc compared to the compiler.
Resolve that by stripping out the include dirs, where specified for
the moc command line to, and then appending them at the end. Note that
the order of the appended implicit include directories is the order
they are specified in the CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, not
the order specified by the user.

Stephen Kelly 1714c27a74 Process generator expressions for 'system' include directories.
Since commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property., 2012-09-18), it is possible to use
generator expressions with the include_directories command.

As that command can also have a SYSTEM argument, ensure that the
result of using that argument with generator expressions gives a
sane result.

Stephen Kelly 3581b96caa Process the INTERFACE_PIC property from linked dependencies
This allows a dependee to inform a target that it should have its
POSITION_INDEPENDENT_CODE property set to ON, or OFF. The value of
the POSITION_INDEPENDENT_CODE property, if set, must be consistent
with any INTERFACE_POSITION_INDEPENDENT_CODE properties on dependees.

Add a test covering the consistency checks on platforms where they run.

Refactoring in commit 8d674e78 (Ninja: move -LIBPATH behind -link

David Cole 7ae7d66503 NMake: Fix problem with empty DEPENDS args (#13392)
add_custom_command can have empty DEPENDS arguments, which
was triggering invalid makefile generation for the NMake
Makefiles generator. We were mistakenly emitting the build
directory appended with "/" plus the empty string... which
was then translated to a string ending in \" in build.make...
which nmake choked on.

The solution is not to emit any dependency when the input
DEPENDS is the empty string. Return early from GetRealDependency
in this empty input case.

Stephen Kelly 95d590ddba GenEx: Create cmGeneratorTargets for imported targets.
We're going to need to link to them, and all the linking API is moving
to cmGeneratorTarget.

Skip imported targets when iterating over cmGeneratorTargets in places
where we only want targets we build.  The GetGeneratorTargets result now
includes IMPORTED targets where it didn't before.  The GetTargets
result, which was what used to be called in these methods does not
include IMPORTED targets.  This doesn't relate to any known bugs, but in
some future uses of GetGeneratorTargets it will be important, so
starting the convention and being deliberate now is a good idea.
