Since commit e015df7d (...delete CMakeFiles directory when cache is
deleted, 2006-02-20) we deleted the files in the CMakeFiles directory
when deleting CMakeCache.txt in order to reset the build tree to a fresh
state. This allowed commit fd33bf93 (fix for bug 6102, allow users to
change the compiler, 2007-12-13) to delete CMakeCache.txt when the user
changes the compiler and CMakeFiles/CMake<lang>Compiler.cmake and other
platform information files would go with it to allow a fresh start.
Then commit 7195aca5 (Make platform information files specific to the
CMake version, 2012-08-24) moved the platform information files to a
subdirectory e.g. CMakeFiles/<version>/CMake<lang>Compiler.cmake where
<version> is the current CMake version. This causes the compiler change
logic to fail to remove all old compiler information. Then on the next
configuration CMake<lang>Compiler.cmake would set CMAKE_<lang>_COMPILER
back to the old value and re-trigger the compiler change logic. This
causes an infinite loop of cache deletion and compiler reset.
Fix this simply by teaching cmCacheManager::DeleteCache to remove the
entire CMakeFiles directory recursively whenever it removes an existing
CMakeCache.txt. This fully resets the build tree to configure with a
fresh compiler.
Since Xcode doesn't sort the files on its own, let's sort them in our
generator to make navigation easier. Visual Studio, QtCreator, and
kdevelop all display files sorted.

The GNU compiler front-ends on AIX invoke the linker with flags of the
form "-L/path/to/gnu/runtime/lib" to tell ld where to find the language
runtime libraries. They depend on the default libpath behavior
documented in "man ld" to add the -L paths also to the runtime libpath
so the dynamic loader can find the language runtime libraries. This
differs from platforms whose linkers have distinct -rpath flags that
non-system compilers can use to tell the dynamic loader where to find
their language runtime libraries.
Since commit 96fd5909 (Implement linking with paths to library files,
2008-01-22) CMake always passes "-Wl,-blibpath:" followed by any
project-defined RPATH plus "/usr/lib:/lib" in order to explicitly set
the runtime libpath and avoid getting all the project -L paths in the
runtime libpath. The explicit libpath prevents the GNU compiler runtime
library -L paths from being placed in the libpath and then the dynamic
loader fails to find the language runtime libraries.
CMake already detects the implicit link directories for each language
since commit 07ea19ad (Implicit link info for C, CXX, and Fortran,
2009-07-23). Add the implicit link directories to the explicit runtime
libpath for GNU compilers on AIX to fix this use case.
Since commit c70beb4b (change the default borland stack size, 2003-05-05),
commit 1b572eb9 (remove -H flags, 2003-05-08), and commit 2d411398 (Stack size
in generated programs should be 10 meg, 2003-06-12) CMake adds link flags to
select a 10MB stack. At the time this was for consistency with our behavior on
MS, but that was recently removed by commit 51af1da3 (Remove "/STACK:10000000"
from default linker flags, 2012-11-23).
Change our Embarcadero link flags to select the default stack and heap settings
according to the compiler documentation. This is more reliable than leaving
the flags out completely as it has been reported that the linker does not
always use its documented defaults.

This reverts commit 2c3654c3de.
The removal of some tests added in commit 77cecb77 (Add includes and compile
definitions with target_link_libraries., 2012-11-05) are also squashed
into this commit.
This is a partial revert of commit 77cecb77 (Add includes and compile
definitions with target_link_libraries., 2012-11-05).
As the interface includes and defines are now determined by the link
closure, there is no need to populate the corresponding properties
explicitly.
After evaluating the INTERFACE_INCLUDE_DIRECTORIES, of a target in a
generator expression, also read the INTERFACE_INCLUDE_DIRECTORIES of
its link interface dependencies.
That means that code such as this will result in the 'user' target
using /bar/include and /foo/include:
add_library(foo ...)
target_include_directories(foo INTERFACE /foo/include)
add_library(bar ...)
target_include_directories(bar INTERFACE /bar/include)
target_link_libraries(bar LINK_PUBLIC foo)
add_executable(user ...)
target_include_directories(user PRIVATE
$<TARGET_PROPERTY:bar,INTERFACE_INCLUDE_DIRECTORIES>)
Also process the interface include directories from direct link
dependencies for in-build targets.
The situation is similar for the INTERFACE_COMPILE_DEFINITIONS. The
include directories related code is currently more complex because
we also need to store a backtrace at configure-time for the purpose
of debugging includes. The compile definitions related code will use
the same pattern in the future.
This is not a change in behavior, as existing code has the same effect,
but that existing code will be removed in follow-up commits.
Since commit 34c882a9 (Allow VS 7 project Rebuild and Solution Rebuild to
work, 2007-11-10) we use a "CMakeFiles/generated.stamp" and some
associated files in the build tree to avoid re-running CMake when the
inputs have not changed but VS has cleaned the outputs it knows about.
When we do not really need to re-run we restore the generated.stamp file.
The non-re-run case can happen in multiple targets in parallel in VS >= 10
so we must restore the file atomically to avoid races. Write the stamp
file to a random temporary name and then atomically rename it to the real
stamp file.
