Running `Utilities/Scripts/BoostScanDeps.cmake` with the Boost 1.70.0
sources shows that the `timer` component no longer depends on `system`.
This is consistent with upstream Boost Timer commit `43eecbd071`.
Fix logic added by commit a7d853868b (FindGLEW: Update implementation,
2019-03-13, v3.15.0-rc1~375^2~1) on macOS. macOS is recognized as both
UNIX and APPLE. Consequently, the library suffix for shared and static
library was set, respectively, as `.so` and `.a`, just like UNIX systems.
Fix this by properly checking the OS type.

Since commit d44c0db0b2 (clang: setup correct configuration in gnu mode,
2019-02-20, v3.15.0-rc1~41^2~5) our Clang compiler information modules
need the `CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` variable that we
compute during compiler detection. However, some existing toolchain
files set our internal `CMAKE_<LANG>_COMPILER_ID_RUN` variables and
block that detection, but do not set the new frontend variant variable.
Help them out by setting `CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` anyway.
Fixes: #19515, #19539
The frontend variant detection logic added by commit 53fbe23f3f (clang:
introduce CMAKE_<lang>_COMPILER_FRONTEND_VARIANT, 2019-02-20,
v3.15.0-rc1~41^2~8) assumes that `clang-cl` only runs on a Windows host.
It is also available on non-Windows hosts. Fix the condition.

In commit f7eaa342de (FindMPI: Store imported target link flags as a
list instead of a string, 2019-06-14, v3.15.0-rc2~2^2) we used
`separate_arguments` to parse the extracted link flags and add them to
`INTERFACE_LINK_LIBRARIES`. That property is not meant for link flags
and CMake may de-duplicate them. This is particularly problematic for
flags like `-Wl,-rpath -Wl,/path1 -Wl,-rpath -Wl,/path2`.
In commit 39c572c9c9 (FindMPI: Updated to use INTERFACE_LINK_OPTIONS,
2019-06-24) we moved the parsed flags over to `INTERFACE_LINK_OPTIONS`,
but that may still perform de-duplication. Avoid the parsing and
de-duplication of flags by passing the original string via `SHELL:`
instead.

Since commit d44c0db0b2 (clang: setup correct configuration in gnu mode,
2019-02-20, v3.15.0-rc1~41^2~5) we support the GNU-like Clang that
targets the MSVC ABI. However, Clang cannot compile with the MSVC
standard library unless it runs in a mode aware of C++14 (since MSVC
itself does not even have a lower mode). When `CMAKE_CXX_STANDARD` is
set to 98 or 11, use C++14 anyway.
Since Clang's default mode is aware of C++14, another option is to not
add any flags for 98 or 11. However, if a future Clang version ever
defaults to a higher C++ standard, setting the standard to 98 or 11
should at least not use a mode higher than 14.
Also revert test updates from commit 4819ff9647 (Tests: fix failures
with gnu mode clang on windows, 2019-03-21, v3.15.0-rc1~41^2~3) that
were meant to work around the standard selection problem.

Since VS 2019, the v141 toolset redistributables can be found in
either the VS 2019 or VS 2017 install directory. Update the logic
to search multiple versions of VS.
Fixes: #19488
Fix the toolset v143 check from commit 33ee779330 (IRSL: Fix discovery
of VS 2019 v142 toolset redistributables, 2019-04-03, v3.14.2~6^2) to
check the correct variable.
The Swift driver recently learnt how to generate static libraries using
the `-static` flag. This enables us to generate proper static libraries
with dependency tracking with Swift as well.
This changes the behaviour of the generators to use a per-language
library search path flag. This is needed for multi-language projects
with different compilers (e.g. cl + gfortran). Since the adjusted
variable has been part of the user settings, we control this based on a
policy.
Fixes: #19307
Now that the working directory is in the build tree, relative input
paths must be converted to an absolute path to remain relative to the
source directory.
Fixes: #19472
Update parsing logic from commit 5990ecb741 (Compute implicit include
directories from compiler output, 2018-12-07, v3.14.0-rc1~108^2)
to handle the quoting behavior caused by the `-hlist=` flag.
Define `CMAKE_Fortran_SUBMODULE_{SEP,EXT}` for the Cray Fortran
compiler. Use an empty separator to tell CMake that this compiler does
not use the enclosing module name as a prefix on submodule files.
Issue: #18925
Since commit 368bcba28a (FindPostgreSQL: Find debug lib, imported
configs, 2019-05-09, v3.15.0-rc1~93^2) the `PostgreSQL_LIBRARY` variable
may contain a list and therefore should not be passed to the
`get_filename_component` command directly. Instead spell out the logic
to compute `PostgreSQL_LIBRARY_DIR` from one of the per-configuration
variables.
Fixes: #19444
In commit fb3370b6a1 (MSVC: Add abstraction for runtime library
selection, 2019-04-10, v3.15.0-rc1~229^2) we overlooked updating flags
for CUDA on Windows, where nvcc uses MSVC as the host compiler. Add
them now and update the MSVCRuntimeLibrary test to cover CUDA.
Fixes: #19428
In commit c4b4d8b3a6 (POSITION_INDEPENDENT_CODE: Manage link flags for
executables, 2018-10-02, v3.14.0-rc1~395^2) we accidentally removed our
Android-specific logic for PIE under the CMP0083 OLD behavior. Restore
it and also implement Android-specific logic for CMP0083 NEW behavior.
Fixes: #19393
There is no need to use a CamelCase executable name since it will be
handled gracefully on Windows anyway. This change allow support for
Linux system, in particular Debian distribution where the binary is
called `nuget`.
The `item` variable was the loop variable in the old code prior to
commit 3dfc8b9bd6 (GetPrerequisites: use if(IN_LIST) instead of foreach,
2019-05-09). The function argument `value` should be used instead.
