Intel classic compilers generate erroneous dependencies when gcc style
is used with paths containing spaces. So, fall back to the old way to
generate dependencies by using option /showIncludes.
Fixes: #23948
In commit a624a3e1b3 (Ninja: Use deps=gcc for Intel Compiler on Windows,
2019-01-30, v3.14.0-rc1~30^2) we forgot to account for commit 6d74e7870b
(Ninja: Add dependencies on system-provided header files, 2016-03-15,
v3.6.0-rc1~265^2).
Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.
The consolidation uses the same approach as `CMake` dependencies management.
Fixes: #21321
These changes are in preparation of compiler generated dependencies support
for Makefiles generators
* compiler output and dependency target can be different for Makefiles generators
* resolve inconsistency naming for dependency file place-holder
Ninja 1.9 supports the depfile format generated by this compiler.
Use `deps = gcc` when the version of Ninja is new enough.
Unfortunately the Intel Compiler for Windows does not properly
escape spaces in paths written to a depfile so if there is a
space in the path we must still fall back to `deps = msvc`.
Fixes: #18855
Teach CMake(C|CXX|Fortran)CompilerId* to report the MSVC version
simulated by the Intel compiler, if any. Refactor the Windows-Intel
platform information helper module to load Windows-MSVC instead of
duplicating the information. Teach Windows-MSVC to understand when
it is loaded as the simulated Fortran compiler (its preprocessor is
simulated).
Use of the deprecated option with Intel 2011 produces
icl: command line remark #10010: option '/GX' is deprecated and will
be removed in a future release. See '/help deprecated'
so use its replacement option which has been supported for several
older versions anyway.
This moves Intel compiler info on Windows into new-style modules
Platform/Windows-Intel-<lang>.cmake
using language-independent helper module
Platform/Windows-Intel.cmake
to define macros consolidating the information.
