Dragos Carp e65c788767 CMakeDetermineCompilerId: Load src from CMAKE_MODULE_PATH (#14481)

Brad King 6007f7ca01 CMakeDetermineCompilerId: Always use compiler detected from IDE
When compiler id detection also provides a CMAKE_<LANG>_COMPILER
value, use it unconditionally.  It is known to be the compiler
that is actually in use by IDE builds in VS and Xcode.  Do not
let a stray cache entry try to say otherwise.

Brad King 705ae00491 Quote ${CMAKE_<LANG>_COMPILER} while enabling a language
Even though this variable gets set to CMAKE_<LANG>_COMPILER-NOTFOUND when
the compiler is not found, CMake<LANG>Compiler.cmake gets removed by
cmGlobalGenerator::EnableLanguage so in try compiles the value is empty.
Quote references to the variable in

 Modules/CMake(C|CXX|Fortran)Information.cmake
 Modules/CMakeDetermineCompilerId.cmake

to avoid dropping arguments from commands that expect them.

Brad King 18a253732d CMakeDetermineCompilerId: Do not test vendor without a compiler

it to determine the compiler vendor.

Brad King 1b7117a824 VS 6: Do not try Intel Fortran .vfproj file with msdev
Teach CMakeDetermineCompilerId to skip trying to build a .vfproj
file for Intel Fortran under Visual Studio 6.  The msdev command-line
build produces a popup error dialog that hangs the configuration.

Brad King af40e8c312 VS: Detect Intel Fortran compiler id and version

Brad King 2d36c9ab60 CMakeDetermineCompilerId: Fix Intel Fortran compiler id detection
The Intel Fortran compiler needs the /fpp option to enable C
preprocessing.  Without the option the compiler may warn and ignore
preprocessor lines instead of failing with an error.  Detect the
warning and treat it as failure so that we move on to try /fpp and
detect the correct id.  Without this it works only by luck because
Intel is the first compiler id in our detection source file.

Brad King 51ab85c398 CMakeDetermineCompilerId: Add notion of "simulated" id/version
Some compilers try to simulate other compilers as a drop-in replacement
supporting all the same command-line options and predefined preprocessor
macros.  In such cases it will be useful to have CMake load the compiler
information files for the simulated compiler instead of duplicating the
information.  Teach CMakeDetermineCompilerId to extract the simulated
compiler id and version when the compiler id detection provides it.

Patrick Gansterer 8bb3b3d344 VS: Use version-specific subsystem for WinCE compiler id (#14440)
The subsystem must be set to WINDWOSCE for some SDKs to link an
executable. Set it to 9 for VS2005 and to 8 for VS2008, since the

When the VS IDE build output setting

suffix on the CMAKE_<lang>_COMPILER= line used to extract the compiler
executable location.  Strip this suffix before checking that the
reported location exists.

Patrick Gansterer b02f09d434 VS: Replace ArchitectureId with PlatformName
Since we do not need the information about the target architecture
we can use the PlatformName only to specify the this information.
This also removes setting of the MSVC_*_ARCHITECTURE_ID variable
which is not required, because this variable gets set by the
compiler detection code in CMAKE_DETERMINE_COMPILER_ID_CHECK().

Patrick Gansterer 60e568cf79 VS10: Do not set the TargetMachine when detecting the compiler

maintaining the mapping to the platform name.

Brad King 7195aca54f Make platform information files specific to the CMake version
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use.  The
method of detection and the exact results store varies across CMake
versions as things improve.  This leads to problems when loading files
configured by a different version of CMake.  Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files.  This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).

Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version.  Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake.  Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.

Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose.  The new variable points
at the version-specific directory while the old variable did not.

Brad King 965a69dcaa Xcode: Detect the compiler id and tool location

the full path to the compiler tool from the xcodebuild output.

Brad King 9a9e1ee98d CMakeDetermineCompilerId: Prepare to detect IDE compiler id
Teach CMAKE_DETERMINE_COMPILER_ID to check for variable
CMAKE_${lang}_COMPILER_ID_TOOL after CMAKE_DETERMINE_COMPILER_ID_BUILD
to use as CMAKE_${lang}_COMPILER since it will not be known until after
the IDE runs.

In CMAKE_DETERMINE_COMPILER_ID_BUILD prepare a cascading "if" so we can
use a generator-specific method to compile the identification source
file.  Leave "if(0)" as a placeholder for now and put the direct
compiler invocation in "else()".  After running the compiler to build
the compiler identification source we file(GLOB) the list of output
files as candidates for extracting the compiler information.  An IDE may
create directories, so exclude exclude directories from this list.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments

Brad King fa7141f5ad Add framework to detect compiler version with its id (#12408)
Teach CMakePlatformId.h to construct an "INFO:compiler_version[]" string
literal from macros COMPILER_VERSION_(MAJOR|MINOR|PATCH|TWEAK) to be
defined in CMake(C|CXX)CompilerId.(c|cpp) for each compiler.  Provide
conversion macros DEC() and HEX() to decode decimal or hex digits from
integer values.  Parse the version out of the compiler id binary along
with the other INFO values already present.

Store the result in variable CMAKE_<LANG>_COMPILER_VERSION in the format
"major[.minor[.patch[.tweak]]]".  Save the value persistently in
CMake(C|CXX)Compiler.cmake in the build tree.  Document the variable for
internal use since we do not set it everywhere yet.

Report the compiler version on the compiler id result line e.g.

  The C compiler identification is GNU 4.5.2

Report CMAKE_(C|CXX)_COMPILER_(ID|VERSION) in SystemInformation test.

Alex Neundorf e6c9bc267b Add timeout to execute_process() in CMAKE_DETERMINE_COMPILER_ID().
In CMAKE_DETERMINE_COMPILER_ID_VENDOR() the compiler is called with various
arguments. In some cases, this can make the compiler hang and wait
forever for input (e.g. "as -v"). That's why add an timeout
so it terminates finally. 10 seconds should be more than enough,
this is the time it takes to startup the compiler, which is
usually quite fast.

Alex Neundorf b333779e34 Detect a COMPILER_ID also for ASM.
For assembler, the "compiler ID" cannot be detected by "compiling" a
source file, since there is not source file all assemblers understand.
Instead the function CMAKE_DETERMINE_COMPILER_ID_VENDOR() is used to
run the assembler and check its output.
For this the CMAKE_DETERMINE_COMPILER_ID_VENDOR() function had to be
extended so that it creates the run directory if it doesn't exist yet.

In CMakeASMInformation.cmake now also CMAKE_ASM_COMPILER_ID is used
(but there are no such files yet, will come with the support for the
IAR toolchain).
