This is a near-total rewrite of FindMPI implementing the following
features:
Environmental improvements:
- C++ settings can now be picked from C settings if no dedicated C++
settings are found (some installs of IBM Platform MPI)
- Fortran settings can now be found on MPICH-1, MVAPICH-1, Microsoft
MPI and MPICH-2 on Windows.
- Improved flag procession logic: Flags related to security enhancements
of MPI itself, and unrelated to MPI usage (-fstack-protector-strong on
e.g. RHEL 7 for MPICH and MVAPICH) will be filtered out properly now.
-pthread is now being handled. -fno-strict-aliasing, which may be needed
while compiling MVAPICH (e.g. RHEL 7's MVAPICH package) is also
filtered.
Features added:
- MPI version can be determined for each language and is exposed as the
package version
- MPI functionality is being tested to ensure the correctness of
settings
- MPI-2 C++ bindings can be suppressed if desired by the project or
user. For older MPIs, this often resolves issues and eliminated the
infamous SEEK_SET trouble.
- MPI-2 C++ bindings are now being searched for and exposed by a
variable if detected.
- Fortran support now does not make assumptions over the MPI present and
works with ILP64 MPI implementations.
- Fortran now exposes which bindings (mpif.h, mpi/mpi_f08 modules) are
available
- MPI detection can now work hybridly, which for example permits using the
Fortran modules shipped with some compiler suites together with MPI
(e.g. PGI on Windows shipping MSMPI modules)
- Ability to determine MPI library version (*requires* try_run, caution)
upon request
- Ability to determine Fortran capabilities from MPI-3 for each of the
bindings (subarrays, asynchronous attribute protecting entities) (also
requires try_run)
Fine grained control over the search process:
- Possibility to selectively enable and disable steps like compiler
wrapper search and guessing. Permits picking Microsoft MPI over Intel
MPI if both are loaded (previously not possible without removing the
IMPI compiler wrappers from the environment)
- Ability to pick MPICH2 over MSMPI (previously the first one located
was taken)
- A user may now pass compiler flags to the compiler wrapper script,
enabling much more flexibility. This permits for example linking the
Intel MPI debug runtime, static linking, ILP64 with Fortran,
linking tracing, ...
- A user may define a suffix for all MPI binaries that are being looked
for (useful on Debian/Ubuntu where the alternative MPI installs are each
appended with their name, e.g. mpicc.mpich and mpicc.lam)
Cache variable improvements
- Instead of the previous plural cache variables a list-of-variables
approach is now in place. Permits correcting individual variables
instead of having to wade through a list, also speeds up the search
process and increases comfort by eliminating duplicate entries in
LIBRARIES over languages
- MPIEXEC was corrected to MPIEXEC_EXECUTABLE in order to fix the
grouping in the CMake GUI for the variable (previously ungrouped)
Add variable `CMAKE_CODEBLOCKS_EXCLUDE_EXTERNAL_FILES` to optionally
exclude files from outside the project root from the project file
written by the CodeBlocks extra generator. This optionally restores
logic that had been removed by commit v2.8.3~40^2 (CodeBlocks Generator:
Do not omit files in the project file listing, 2010-10-05) in response
to QTCREATORBUG-2250.
Issue: #12110Fixes: #17188
The KWSys `SystemTools::SplitProgramFromArgs` implementation goes into
an infinite loop when the value is just " " (a space). Since the
"program path with unquoted spaces plus command-line arguments"
operation it is trying to provide is poorly defined (string parsing
should not depend on filesystem content), just stop using it.
Instead consider the main two use cases the old approach tried to handle:
* The value is the name or absolute path of a program with no quoting
or escaping, but also no command-line arguments. In this case we
can use the value as given with no parsing, and assume no arguments.
* The value is a command-line string containing the program name/path
plus arguments. In this case we now assume that the command line
is properly quoted or escaped.

flang is a Fortran compiler built on top of clang [1]. Because flang
shares a lot of commonalities with clang, the flang module piggybacks
off the clang module and overrides certain options.
Add flang to Fortran compiler auto find list.
Update flang preprocessor macros to differentiate from PGI.
Add Flang-FindBinUtils.

Create a `<LANG>_CPPCHECK` target property (initialized by a
`CMAKE_<LANG>_CPPCHECK` variable) to specify a `cppcheck` command line
to be run along with the compiler.
CMake can now compile as C++11 on all supported platforms. Check that
std::unique_ptr is available and fail early if missing. This will allow
us to use C++11 more broadly in CMake's implementation (previously it
was restricted to the serve mode implementation).

CMake will soon require both C++11 and libuv to build. Neither of
these works on HP-UX, so unfortunately we need to drop support for
the platform until someone can get them working.
Issue: #17137
Add a new gtest_discover_tests function to GoogleTest.cmake,
implementing dynamic test discovery (i.e. tests are discovered by
actually running the test executable and asking for the list of
available tests, which is used to dynamically declare the tests) rather
than the source-parsing approach used by gtest_add_tests. Compared to
the source-parsing approach, this has the advantage of being robust
against users declaring tests in unusual ways, and much better support
for advanced features such as parameterized tests.
A unit test, modeled after the TEST_INCLUDE_DIR[S] test, is also
included. Note that the unit test does not actually require that Google
Test is available. The new functionality does not actually depend on
Google Test as such; it only requires that the test executable lists
tests in the expected format when invoked with --gtest_list_tests, which
the unit test can fake readily.
This lets AUTOMOC and AUTOUIC process GENERATED files which
used to be ignored before.
A new policy CMP0071 ensures that the old behavior of ignoring
GENERATED files is enabled when the CMake compatibility version
CMAKE_MINIMUM_REQUIRED is < 3.10.

Add new directory property TEST_INCLUDE_FILES. This supersedes
TEST_INCLUDE_FILE, though the latter is of course retained for
compatibility.
Basically, this is a list rather than a single file. This allows the
feature to be used by generic utilities without conflicting with local
use.

Optional spaces and/or tabs are now understood between the '#' character
and the 'cmakedefine'/'cmakedefine01' words. This indentation is
preserved in the output lines.
