Somehow using `istringstream` and `operator >>` to parse an integer
crashes on Alpine Linux, at least when compiled with the settings we use
for the official `cmake.org` Linux binaries. Since commit fd0c285b12
(file: Fix types of the OFFSET and LIMIT arguments, 2022-01-04,
v3.23.0-rc1~133^2), this causes the `file(READ)` command to crash when
parsing its `LIMIT` or `OFFSET` argument. Parse the input string with
our dedicated helper to avoid the crash.
Fixes: #23872
When we introduced the `GTest::gmock` and `GTest::gmock_main` targets in
commit 50bf457a0d (FindGTest: Add target for gmock library, 2021-10-17,
v3.23.0-rc1~321^2) we failed to handle the case where GTest isn't found.
Don't construct gmock targets that depend on non-existent gtest targets
when gtest failed to be found.
If we're creating generation objects for imported targets only, we
don't need the export sets. Only compute build file generators
if generating for all targets.

Since commit 2c9e623e31 (Find{BLAS,LAPACK}: Add support for the NVHPC
LAPACK library, 2021-05-05, v3.21.0-rc1~192^2) we try the `-fortranlibs`
option as a dependency of the NVHPC LAPACK. That flag is specific to
the NVHPC/PGI compilers, so use it conditionally with them.
Without this modification, CMake fails to find LAPACK if
- compiler ID is GNU
- `BLA_STATIC` is `ON`
- `BLA_VENDOR` is not defined or set to `All`
Fixes: #23705, #22878
Missing file sets were originally checked at configure time in
install(TARGETS ... EXPORT), but were not checked at generate time. If
a file set was added after install(TARGETS ... EXPORT) was called,
an abortion error was thrown. Check again at generate time to gracefully
display an error message instead of crashing.
Fixes: #23680
Since LCC 1.26.03, compiler developers decided to rename
liblfortran to libgfortran (internal reference: mcstbug#131633),
and despite it's stated that "-llfortran will be automatically
treated as -lgfortran", it actually does not work (and there's
even no symlinks like liblfortran.* -> libgfortran.*); so we
have to explicitly choose which library we have to link in.
Fixes: #23646
The change to `_ep_add_mkdir_command` in commit 5fbac2bb24
(ExternalProject: Move inline scripts to separate files, 2022-01-22,
v3.23.0-rc1~101^2) did not account for the possibility that
`CMAKE_CFG_INTDIR` is `$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)`
instead of just the configuration name. Pass the value into the helper
script on the command line so that the native buildsystem placeholders
are evaluated.
Fixes: #23645
On some Xcode versions, `xcodebuild` may warn:
... xcodebuild[...] [MT] DVTSDK: Warning: SDK path collision for path ...
Teach RunCMake to drop such incidental lines before matching against
expected output.
Xcode 14 no longer accepts an empty signing identity for macOS.
However, Xcode in general does not accept an ad-hoc signing
identity for iOS. Switch based on the target platform.

Since commit 07223c5c27 (Tutorial: Update Step 5 to work on Windows,
2020-02-18, v3.18.0-rc1~655^2) the logic does not work on non-Windows
platforms when cmake is re-run on an existing build tree. It is also
more complicated than we'd like for a tutorial example. Avoid the need
to consider the `m` library case by performing the check as C++.
Since `check_cxx_symbol_exists` cannot handle overloaded functions
like `exp` and `log`, check with `check_cxx_source_compiles` instead.
This also presents a more general-purpose example in the tutorial.
Fixes: #23524
