This is a follow-up to commit b696f78073 (cmDepends: merge dependers of
depend makefile, 2020-12-18). NMake of visual studio has many versions
that not support long line dependencies of make rule.

Since one depender has multiple dependees, depend makefile generated
same depender line by line, to reduce file size and refine make file
parse speed, merge same dependers to one. And add a testcase for
large depend.make which generated source file includes 20000 header
files and run build and incremental build

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.

Previously only occurred per config which broke per-language
system includes.

We have tests for special characters in preprocessor definitions and
custom command line arguments. Add such a test for include directories.
Currently the Makefiles generators do not escape paths in `depend.make`
in all cases, so leave a FIXME comment and skip the test for those.

* Disable the system include unused variable test in ExportImport when
clang is in MSVC compatible mode.
* Disable CxxDialect testcase when clang is in MSVC compatible mode, as
it doesn't support `typeof`.
* Teach Module.WriteCompilerDetectionHeader to treat clang-cl as MSVC.
* Disable the SystemIncludeDirectories testcase within
IncludeDirectories when clang is in MSVC compatible mode.
* Disable the CMakeOnly.CheckCXXCompilerFlag testcase when clang is in
MSVC compatible mode.
* Treat clang-cl as MSVC in LinkOptions.cmake in the try_run and
try_compile testcases.

An effect of the `-isystem` flag is to search the directory after those
specified via `-I` flags. Make behavior more consistent on compilers
that do not have any `-isystem` flag by explicitly moving system include
directories to the end.

We now populate the per-language flags in addition to the header
search paths stored in HEADER_SEARCH_PATHS. This preserves include
paths for GNU assembly files (cmake/cmake#16449) and also provides
SYSTEM include semantics.
Closes: cmake/cmake#15687

Revert commit v3.7.0-rc1~266^2 (Xcode: Obey SYSTEM keyword for includes,
2015-08-31). It worked for C, C++, and Swift but not for GNU Assembly
files for which Xcode has no property to set flags.
Closes: #16449

CMake used to put all header search paths into HEADER_SEARCH_PATHS
attribute. Unfortunately this attribute does not support to declare
a search path as a system include.
As a hack one could add a -isystem /path to the cflags but then include
ordering is not deterministic. A better approach was chosen with this
patch by not filling HEADER_SEARCH_PATHS at all and to populate
the C, C++, and Fortran flags directly. The include paths used by
Xcode should be now identical to the ones used by Unix Makefiles and
Ninja generator.

Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify
system include directories for for `<LANG>` compiler command lines.
This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.

Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang. Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.
Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.

Exclude Ninja and Xcode from the CMP0021 test
They do not behave the same as the makefile generator with
relative paths.
Don't overwrite the header file for in-source builds.

Unlike other target properties, this does not have a corresponding
non-INTERFACE variant.
This allows propagation of system attribute on include directories
from link dependents.

This is a regression introduced in commit 0d46e9a0 (Store includes
from the same include_directories call together., 2013-01-20).

This was broken by commit 18a3195a (Keep track of INCLUDE_DIRECTORIES
as a vector of structs., 2012-11-19).

Eliminate callers of cmMakefile::GetIncludeDirectories.
All callers of GetIncludeDirectories should go through the local generator
object.
Only the local generator calls cmTarget::GetIncludeDirectories directly.
|
| |
|
| |
|

|
|
This fix adds a test for this case for all generators.
