Store the Android API level in CMAKE_SYSTEM_VERSION. If it is not
provided by the user, initialize it from CMAKE_ANDROID_API or fall back
to finding the latest available in the NDK.
Support for NVIDIA Nsight Tegra Visual Studio Edition was previously
implemented in the CMake VS IDE generators. Avoid interfering with
that functionality for now. Later we may try to integrate this.
Provide a way for Platform/<os>-Determine-<lang>.cmake modules to save
platform-specific information about the compiler in the configured
CMake<lang>Compiler.cmake modules.
Once CMAKE_SYSTEM_NAME is known, load a platform-specific
Platform/<os>-Determine
module in order to enable custom determination of the other settings
needed for the CMakeSystem module (e.g. CMAKE_SYSTEM_PROCESSOR). Also
add a hook in Modules/CMakeSystem.cmake.in to allow platform-specific
information to be saved.
CMake used to put all header search paths into HEADER_SEARCH_PATHS
attribute. Unfortunately this attribute does not support to declare
a search path as a system include.
As a hack one could add a -isystem /path to the cflags but then include
ordering is not deterministic. A better approach was chosen with this
patch by not filling HEADER_SEARCH_PATHS at all and to populate
the C, C++, and Fortran flags directly. The include paths used by
Xcode should be now identical to the ones used by Unix Makefiles and
Ninja generator.
The Numerical Algorithms Group (NAG) Fortran compiler documents -PIC for
position-independent code and does not have a separate option for PIE.
We added `-PIC` for PIC in commit v2.8.11~174^2 (NAG: Use -PIC for
Fortran position-independent code, 2013-02-18). Follow up for PIE.
Closes: #16236
When using `grep` to filter the output, add the `-a` flag to tell
it never to treat the output as binary. Otherwise when LANG != C
in the environment the non-ascii text may break the filter.
Find modules only detect Debug and Release configurations. All other
configurations will fall back to the configuration listed as the first
entry in `IMPORTED_CONFIGURATIONS`. Switch the order so that `Release`
is listed first, as this is a better fallback than `Debug` for the
`RelWithDebInfo` and `MinSizeRel` configurations. See issue #16091.
This approach is recommended by documentation in `cmake-developer(7)`
added by commit v3.2.0-rc1~286^2~1 (Help: Document IMPORTED_CONFIGURATIONS
target property for Find modules, 2014-12-04).
088f14eb Intel-C: standard flags are also supported in 12.0
27a3ca15 Intel-C: support gnu89 and gnu99 extension flags
cc223e1e Intel-C: declare support for gnu11
Without extensions, functions like `strdup` are not available since they
are actually controlled by feature flags such as _SVID_SOURCE and
_BSD_SOURCE. When using `-std=c11` on Intel, none of these flags are
set, so the functions are not declared properly leading to compile
errors.

Do not consider a top-level `.DS_Store` file when deciding whether a
tarball contains exactly one directory whose contents should be used as
the resulting top-level of the extraction.
Fixes#16218.

This flag is needed for the `<LANG>_VISIBILITY_PRESET` target property.
It has been supported since GCC 4.0, not 4.2 as we previously recorded.
Fixes#16222.
