Beginning with the 19.06 release of the Cray Programming Environment, the
default linking mode on XC Cray systems is dynamic instead of static.
This updates the CrayPrgEnv compiler wrappers to detect the PE version
being used and behave accordingly.
In commit e374b9f1eb (FindMPI: Restore MPI_<LANG>_COMPILE_FLAGS as a
command-line string, 2018-09-10, v3.12.3~6^2) we tried to restore the
compile flags but accidentally inverted the arguments to `list(JOIN)`
causing both `MPI_<LANG>_COMPILE_FLAGS` and `MPI_<LANG>_COMPILE_OPTIONS`
to be empty.
Issue: #18349
In commit fb3370b6a1 (MSVC: Add abstraction for runtime library
selection, 2019-04-10, v3.15.0-rc1~229^2) we overlooked updating flags
for Flang on Windows. Add them now and update the MSVCRuntimeLibrary
Fortran test to work with Flang. Base the flags on those we already
use for the GNU-like Clang targeting the MSVC ABI.

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.
Fixes: #19542
When `CMAKE_FIND_PACKAGE_PREFER_CONFIG` mode was set to `ON`, failure to
find a package was fatal even if it was not `REQUIRED`. Fix this and
add a test case.
Fixes: #19557
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
Since commit e89ad0f94e (install: Allow installing targets created in
another directory, 2018-06-18, v3.13.0-rc1~407^2) we support calling
`install(TARGETS)` for targets created in another directory. However,
install generators are associated with the directory in which the call
to `install()` appears. This may not be the same directory in which the
target is defined. Record in each target the list of install generators
it has.
Fixes: #19546
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.
Fixes: #19544
Fix the check added in commit 8d93815d20 (source_group command ensures
that FILES arguments are actually files, 2019-04-25, v3.15.0-rc1~195^2)
to convert to an absolute path before checking for existence.
Also simplify the conversion to an absolute path.
Fixes: #19454
The mapping for this flag was added by commit 43aa632f57 (VS: Populate
`-Qspectre-` flag table entry for v142, 2019-01-24, v3.14.0-rc1~74^2~7).
However, it did not do anything because the special logic added by
commit bb60ed6e72 (VS: Add flag table entry for -Qspectre, 2018-10-08,
v3.13.0-rc1~4^2) to move the `SpectreMitigation` element from
`ClCompile` to the top level only handled the presence of the setting
and not its value. Extend the special logic to carry the value too.
Fixes: #19535
The check added in commit b06f4c8a74 (Swift: disallow WIN32_EXECUTABLE
properties, 2019-05-31, v3.15.0-rc1~9^2) makes sense only for
executables because the `WIN32_EXECUTABLE` property is defined only for
them. Running the check on other target types, particularly those that
do not link such as INTERFACE libraries, violates internal assumptions.
In particular, `GetLinkerLanguage` should not be called on such targets.
Fixes: #19528
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.
Fixes: #19516
Since commit a13a5c948e (Replace use of CollapseCombinedPath with
CollapseFullPath, 2019-03-19, v3.15.0-rc1~361^2~1), one code path now
calls `CollapseFullPath` with a base path that may be relative.
Backport KWSys commit c6f8e24a3 (SystemTools: Fix CollapseFullPath with
relative base path, 2019-07-24) to handle such base paths.
This case occurs when a build tree is placed in a directory inside a
source tree such that CMake is willing to generate a relative path from
the build tree to the source tree. Add a test covering this case.
Fixes: #19507
Revert commit a2a90f41e3 (Tests: require C++14 for the Tutorial,
2019-03-21, v3.15.0-rc1~41^2~2). In commit d50b31be35 (Clang: For MSVC
ABI do not use modes older than C++14, 2019-07-23) we fixed the C++
standard selection for GNU-like Clang with the MSVC ABI so the test code
itself no longer needs to do it. In particular, changing the tests in
this way broke the tutorial's narrative.
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.
Fixes: #19496
In commit fec441ec17 (Teach CROSSCOMPILING_EMULATOR to support
arguments, 2019-05-30, v3.15.0-rc1~6^2) the new member
`cmCustomCommandGenerator::EmulatorsWithArguments` was not initialized
to the proper size. Fix this and add a test case covering the crash
that could occur with multiple commands where an emulator appears only
in a later command.

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.
