Avoid passing the output of our `try_compile` through a macro argument.
Macro invocations re-parse their arguments and so should not be given
arbitrary content that may contain backslashes and such.
Instead pass a simple message. This is also more readable in the case
that the macro generates a message itself. After the macro returns,
report the real output directly to the variable named by our caller.
Also record the output in a log file as other checks do on failure.

Simplify the test for whether a `RESULT` argument was given to the
`check_ipo_supported` call. Also do not set an empty variable name
if `OUTPUT` was not given.
By adding the "if (NOT BLAS_LIBRARIES)" statement to the Intel MKL
detection code block we have unintentionally turned Intel MKL from
the most preferred into the least preferred BLAS library. To fix
this issue the Intel MKL detection code block needs to be moved
forward to make it the first explicit BLAS library we test for.
This is change does just that and re-instates Intel MKL as the
most preferred explicit BLAS library.
All non-Intel BLAS library detection blocks have an if-statement
"if (NOT BLAS_LIBRARIES)" to ensure that if a BLAS library was
found we are not going to try and find another one. This causes
a problem when we have already found that we do not need to specify
a BLAS library, as the Intel MKL library takes precedence over
everything. Introducing the "if (NOT BLAS_LIBRARIES)" if-statement
fixes this problem.
Run the Check_Fortran_Libraries macro with an *empty* list of libraries
to detect whether the compiler implicitly links BLAS. If this works,
set `BLAS_LIBRARIES` to a placeholder value to get through the rest of
our logic. At the end replace the placeholder by a real empty string
again to report to callers.
AUTOMOC used to fail to generate ``moc_predefs.h`` when ``ccache`` was used
as a compiler starter by e.g. configuring a project with the environment
variable CXX="ccache g++".
The reason was that ``CMAKE_<LANG>_COMPILER_ARG1`` wasn't respected in the
definition of ``CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND`` for various
compilers. This is fixed by this patch.
Fixes#17275.
NDK r18 drops GCC toolchains and some STL types. We need to choose a
clang toolchain by default when no gcc toolchains are available. Switch
the STL type default to `c++_static` when the old `gnustl_static`
default is not available.
Update the test suite to not run tests for STL types that do not exist.
Also do not expect the gcc toolchain `cpp` tool to be available because
r18 does not provide it. Also teach it to tolerate `gcc -dumpmachine`
output like `arm--linux-android` that differs from the toolchain prefix.

Use `curand_static` to identify directories containing device libraries
because `cublas_device` is deprecated and will be removed in the future.

Since commit v3.12.0-rc1~332^2 (FindCUDA/select_compute_arch: Add
support for CUDA as a language, 2018-03-15) this module sets
`CUDA_VERSION` based on `CMAKE_CUDA_COMPILER_VERSION` when the language
is enabled. Limit it to two components for consistency with the
normal `FindCUDA` documentation and behavior.
Fixes: #18231
The XL compiler does not have a dedicated "pie" option so use at least
`-qpic`. This missing setting was exposed by the `ExportImport` and
`PositionIndependentTargets` tests with XL on an ELF platform.
