When crosscompiling we pass the sysroot.
We need to try various architecture flags. Clang doesn't automatically
select one that works. First try the ones that are more likely to work
for modern installations:
* <=sm_50 is deprecated since CUDA 10.2, try sm_52 first for
future compatibility.
* <=sm_20 is removed since CUDA 9.0, try sm_30.
Otherwise fallback to Clang's current default. Currently that's `sm_20`,
the lowest it supports.
Separable compilation isn't supported yet.
Fixes: #16586
Both set_source_files_properties() and set_property(SOURCE) now accept
two new optional arguments: DIRECTORY and TARGET_DIRECTORY.
The DIRECTORY option takes a list of relative or absolute paths
pointing to processed source directories (add_subdirectory was
already called on them).
These paths specify directory scopes where the source file properties
will be set. Previously the scope was always the currently processed
source directory.
Similarly TARGET_DIRECTORY takes a list of targets, whose source
directories will be used as the list of scopes where to set the
source file properties.
get_property() and get_source_file_property() also get the same
new arguments, except only one value can be specified instead
of a list.
Fixes: #20128
For large projects, the default bzip2 compression of gcov data is
prohibitively expensively (could take several hours). Introduce options
that allow the consumer to choose between file size and compression time.
Add a new optional argument `TARBALL_COMPRESSION` for the macro
`ctest_coverage_collect_gcov`. This option accepts the values `GZIP`,
`BZIP2`, `XZ`, `FROM_EXT`, or an expression that evaluates to `FALSE`.
The default value is `BZIP2` to preserve prior behavior.
Fixes: #20593
Add a `VS_PLATFORM_TOOLSET` target property to set `PlatformToolset` in
the `.vcxproj` file for specific targets. Document that this is safe
only when the named toolset uses the same underlying compiler as the
primary toolset.
Fixes: #17429
Through hint Python_FIND_IMPLEMENTATIONS it is possble to specify, as an
ordered list, which implementations must be searched for.
Currently possible values are:
* CPython
* IronPython
Change the default color for strings from BLUE (which is nearly
illegible on any terminals using the standard color palette which has
been around since at least CGA, almost 40 years ago) to CYAN. Add
ability to customize the colors via an environment variable (inspired by
LS_COLORS and using similar syntax).
Fixes: #20596
This is an old module from when VTK and other Kitware projects drove the
addition of commands and modules into CMake itself. Modern VTK doesn't
need this module and it can be ignored.
This module is kept around so that the ancient VTK versions which use it
are not broken by it. VTK itself stopped using the module in 2012 and
the last usage by an example in VTK was removed in 2020.
Fixes: #20591
On Windows, toolchains like MSVC require a set of environment variables
to be configured for the compiler to work correctly. The scripts that
prepare these environments typically put the compiler's directory ahead
of others in the `PATH`. Teach the Ninja generators to use this as a
heuristic to select the compiler when none is explicitly specified.
This is not necessary with Makefile generators because each toolchain's
environment comes with its own make tool variant, and the corresponding
Makefile generator (e.g. "NMake Makefiles") automatically implies the
matching compiler.
Fixes: #20585
properties LINK_OPTIONS and INTERFACE_LINK_OPTIONS are propagated
to the device link step.
To control which options are selected for normal link and device link steps,
the $<DEVICE_LINK> and $<HOST_LINK> generator expressions can be used.
Fixes: #18265
These generator expressions can only be used in link options properties.
These expressions return the arguments respectively for device and host link
step, otherwise return an empty string.
Simplifies CUDA target architecture handling.
Required for Clang support as Clang doesn't automatically select a supported architecture.
We detect a supported architecture during compiler identification and set CMAKE_CUDA_ARCHITECTURES to it.
Introduces CMP0104 for backwards compatibility with manually setting code generation flags with NVCC.
Implements #17963.
