The `cmLocalGenerator::GetIncludeDirectoriesImplicit` method is called
by `cmQtAutoGenInitializer` to get the compiler's list of implicit
include directories. Since commit 557b2d6e65 (Fix regression in
-I/usr/include exclusion logic, 2019-02-13, v3.14.0-rc2~6^2~2) the
method hard-codes exclusion of `/usr/include` for historical reasons.
However, it should not be reported as a real implicit include directory
unless the compiler really has it.
Refactor the logic to distinguish the hard-coded exclusion of
`/usr/include` from the real list of implicit include directories.

When the current source file is not found the FilePath variable was left
with the previous path content. In case the previous file had less lines
than the current one and there are 'line' entries for the current one
with higher number we ended up in a buffer overflow while indexing the
previous file entry with a line number higher. By clearing the
FilePath, the empty() guard triggers correctly on an empty path and it
avoid modifying the wrong data.
Any `include_directories()` calls in toolchain files are used during our
ABI detection step even though it does not include any system headers.
Since commit 5990ecb741 (Compute implicit include directories from
compiler output, 2018-12-07, v3.14.0-rc1~108^2), that check is also used
to detect implicit include directories. Any `include_directories()` in
a toolchain file are detected as implicit and later excluded from
explicit specification on compiler command lines, thus breaking the
purpose of the calls in the first place.
Fix the implicit include directory detection step to avoid using paths
from `include_directories()` calls in the toolchain file.

Do not process interface libraries in ways that expect build information
to be present internally. This filtering was left out of the extra
generator accidentally when interface libraries were introduced, but it
worked by accident until commit 76ad2ecb50 (Order SYSTEM include
directories after non-system directories, 2018-04-13, v3.12.0-rc1~179^2)
added a code path that was not tolerated.

Since commit c76c1ea208 (find_program: Consider CWD only for paths with
separator, 2018-05-31, v3.13.0-rc1~413^2) we accidentally convert the
leading `//` to just `/` on results with Windows network paths.
This was caused by `CollapseCombinedPath` being less robust than
`CollapseFullPath`. Restore use of the latter but in a way that
preserves the requirement of the above commit to support candidates that
are themselves absolute.

In commit 57e48f16f2 (VS: Add Visual Studio 16 2019 generator,
2019-01-09, v3.14.0-rc1~150^2) and commit 0fd742a6ff (VS: Teach VS 2019
generator to select host tools matching host arch, 2019-01-28,
v3.14.0-rc1~63^2) we intended to select the `x64` target architecture
and `x64` host tools by default on x64 host machines. Fix detection
of a x64 host when CMake itself is a 32-bit x86 process.
The KWSys SystemInformation `Is64Bits` member is not set correctly,
which led to this bug. Pending investigation on the KWSys side,
simply test ourselves via `IsWow64Process`.
Revert commit da402a081b (VS: Use MSBuild matching toolset host
architecture, 2019-01-28, v3.14.0-rc1~50^2). Multiple people have
reported that the 64-bit `amd64/msbuild` tool fails in cases that the
32-bit `msbuild` works. Drop our change pending further investigation
and hopefully a fix to VS.

Require the word "warning" to appear at the start of a line, after
whitespace, or after a `:`. This is the same that CTest launchers use
to match warnings. It avoids matching "warning" inside file paths.

Since commit e89ad0f94e (install: Allow installing targets created in
another directory, 2018-06-18, v3.13.0-rc1~407^2) the `install(TARGETS)`
command may find a global-scoped target outside the calling directory.
Ignore an `IMPORTED GLOBAL` target if it is found in this way. Imported
targets cannot be installed, and trying to do so violates internal
invariants.

Encode `\n` as ` ` to avoid generating a literal newline inside an
XML attribute. This is more readable and also fixes custom commands in
`.csproj` files with VS 2019 RC.

The Intel Fortran `.vfproj` files do support both Fortran and the
Windows Resource compiler (`.rc)` files. Prior to CMake 3.9 we did not
support that, but commit 2c9f35789d (VS: Decide project type by linker
lang as fallback, 2017-03-30, v3.9.0-rc1~340^2) accidentally enabled it.
It was then broken by commit d3d2c3cd49 (VS: Fix Fortran target type
selection when linking C++ targets, 2019-02-04, v3.14.0-rc1~13^2).
Restore support for Fortran+RC in VS projects and add a test case.

The filter in commit e768d96c74 (CUDA: Filter out host link flags during
device linking, 2018-10-22, v3.13.0-rc2~4^2~2^2) removes `-framework`
but not the framework name that comes after it. Revise the logic to
remove both.

A temporary workaround added by commit 626c51f47b (VS: Update for Visual
Studio 2019 Preview 2, 2019-01-24, v3.14.0-rc1~74^2) is no longer needed
as of VS 2019 preview 4.

Make sure `std::cbegin`, `std::cend`, and `std::size` work in C++17 or
C++14 mode before choosing the corresponding standard level for
compiling CMake itself. This helps in cases that the compiler is using
a standard library too old to support the full standard level chosen.
In commit dc6888573d (Pass EXCLUDE_FROM_ALL from directory to targets,
2019-01-15, v3.14.0-rc1~83^2) all `AddNewTarget` call sites were updated
to copy the directory-level `EXCLUDE_FROM_ALL` into the target property
of the same name, except that the one for `include_external_msproject`
was incorrectly missed. Add it now.
Furthermore, refactoring in commit b99129d2d8 (ENH: some code cleanup,
2007-03-12, v2.6.0~2020) accidentally set the `EXCLUDE_FROM_ALL` target
property of `include_external_msproject`-generated targets to `FALSE`
instead of simply leaving it unset. This was not necessary but had no
effect until the above commit gave it a meaning. Drop that.
Fixes: #18986
The original warning pre-dates support for install components.
There are now legitimate scenarios where an install(TARGETS)
command may list a target that is excluded from all, e.g.
hierarchical projects that will never install the component such a
target belongs to.
Fixes: #18938
Since commit 2e91627dea (ParseImplicitIncludeInfo: add Fortran implicit
include handling, 2019-01-25, v3.14.0-rc1~73^2) we actually populate
`CMAKE_Fortran_IMPLICIT_INCLUDE_DIRECTORIES` for the first time. This
value may be useful to project code to pass to other tooling that wants
to preprocess the way Fortran does, so we should compute the value.
However, compilers like `gfortran` do not actually search their own
implicit include directories for `.mod` files. The directories must be
passed via `-I` in order for `.mod` files in them to be found.
Since Fortran has no standard library header files that we need to avoid
overriding, it is safe to *not* filter out implicit include directories
from those passed explicitly via `-I` options. Skip this filtering so
that include directories specified by project code to find `.mod` files
will be searched by the compiler even if they happen to be implicitly
searched by the preprocessor.
Fixes: #18914
This adds the cmQtAutoGenGlobalInitializer::GetExecutableTestOutput method
which caches the output of the called executable and returns the cached value
on any subsequent call.
VS 2019 does not default to the 8.1 SDK as VS 2017 and VS 2015 did.
When `CMAKE_SYSTEM_VERSION` is 8.1 or lower, select the 8.1 SDK
explicitly.

In commit 1293ed8507 (ParseImplicitIncludeInfo: keep implicit incl.
consistent when rerunning cmake, 2019-01-30, v3.14.0-rc1~26^2) we did
not account for `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES`. This
variable lets platform modules or toolchain files specify directories
that are to be explicitly passed as standard include directories. These
include directories are used by the test project from which we extract
implicit include directories so they appear in the parsed results
whether or not the compiler really considers them implicit. Exclude
these entries from the computed implicit include directories since they
are not actually implied by the compiler when we invoke it with
"standard" include directories passed explicitly.
Instead teach the build system generators to treat the "standard"
directories as implicit for purposes of excluding them from appearing
earlier in the compiler command line due to `include_directories` and
`target_include_directories` calls.
Issue: #18936, #18944
`CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` is meant to unconditionally
add explicitly specified include directories to compile lines. In
commit 5f34bdc7f9 (cmLocalGenerator: Refactor
`GetIncludeDirectoriesImplicit` method, 2019-01-25, v3.14.0-rc1~65^2~1)
a condition was accidentally added to exclude implicit include
directories. Drop that condition.
Fixes: #18936
Since commit 7cd65c97fa (Add CMAKE_SYSROOT variable to set --sysroot
when cross compiling., 2013-04-13, v3.0.0-rc1~342^2) we have prefixed
the value of `CMAKE_SYSROOT` to implicit include directories. This was
done because we hard-coded `/usr/include` as an implicit include
directory without accounting for the sysroot. Instead we should prefix
the hard-coded paths when they are constructed. Update the
`Platform/UnixPaths` module to do this as `Platform/Darwin` already
does.
Since commit 5990ecb741 (Compute implicit include directories from
compiler output, 2018-12-07, v3.14.0-rc1~108^2) the values of the
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` variables are computed from
a real compiler invocation so they already account for the sysroot
prefix. In commit 6fc3382944 (Update logic for sysroot in detected
implicit include directories, 2019-02-13, v3.14.0-rc2~6^2) we attempted
to apply the prefix conditionally, but that is incorrect because the
compiler's real implicit include directories are not all under the
sysroot. Instead assume that all implicit include directories in
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` already have the sysroot
prefix if needed. Code that constructs the value must be responsible
for that because it is the only place that knows.
The quoting added by commit 8c5221fb1f (try_compile: Preserve special
characters in COMPILE_DEFINITIONS, 2019-01-21, v3.14.0-rc1~108^2~3)
broke the case that the `COMPILE_DEFINITIONS` value contains a `;`.
Without the quoting the `;` would be generated literally in an unquoted
argument in the test `CMakeLists.txt` file and would then be expanded.
With quoting the `;` is preserved, which is not the old behavior.
Fix this by expanding the `;`-list ahead of time. Add test cases for
behavior with both `#` and `;`.
This was noticed with the PGI compiler where we set
`CMAKE_CXX*_STANDARD_COMPILE_OPTION` to values like `--c++17;-A`. The
symptom had also been observed while preparing commit ef8f237686
(ParseImplicitIncludeInfo: add SunPro Fortran and PGI compiler, Cray
fix, 2019-01-29, v3.14.0-rc1~26^2~2) but was not recognized at the time
as a regression. Revert the workaround added by that commit.
