c307e1c Tests/RunCMake: Allow tests to control build tree behavior
2963c98 Merge branch 'empty-compiler-crash' into compiler-change-cleanup
1df09e5 Delete entire CMakeFiles directory when deleting CMakeCache.txt (#13756)
Add RunCMake.CompilerChange test to cover use of -DCMAKE_C_COMPILER=cc
to change the compiler of an existing build tree. Also test for proper
failure with -DCMAKE_C_COMPILER="" and no CC in the environment.
Generate a unique PBXTargetDependency and PBXContainerItemProxy for
every edge in the dependency graph as required by the Xcode format.
Xcode only accidentally loads project files that re-use the same
PBXTargetDependency for every edge leading to a single target. If one
is removed by hand in the IDE then Xcode may crash due to dangling
references from the others.
Since cmGlobalXCodeGenerator::AddDependTarget is called exactly once for
every edge in the target dependency graph we do not need to keep track
of which edges have been visited to avoid generating duplicates.
The modern cmComputeTargetDepends guarantees there will by no cycles.
Drop the Xcode generator's check which only handled length 1 and 2
cycles anyway.

SublimeClang is a optional plugin to SublimeText and I felt it
shouldn't be part of the generator for the following reasons:
1. Reduces the amount of sublime and sublimeClang specific
code we have to maintain inside CMake.
2. In testing the SublimeClang commands generated did not work
for the VTK project.
For people that do want this feature I recommend that they
looking into https://gist.github.com/robertmaynard/4724705 for a
way to use CMAKE_EXPORT_COMPILE_COMMANDS to generate JSON files
that can be used by SublimeClang.
Since the topic merged to master by commit 34a02846 (Merge topic
'ide-compiler-id', 2012-08-24), these variables are not used by
CMakeDetermine*Compiler.cmake for VS and Xcode generators. Drop the
code that sets them.
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.
