This option has been broken since commit b9f9915516 (cmMakefile: Remove
VarUsageStack., 2015-05-17, v3.3.0-rc1~52^2). That commit removed the
check that an initialized variable has actually been used and caused the
option to warn on every variable ever set. This was not caught by the
test suite because the test for the feature only checked that warnings
appear when needed and not that they do not appear when not needed.
The option was never very practical to use. Remove it to avoid the
runtime cost of usage tracking and checks for every variable (which we
were doing even when the option was not used).
The GLSL SPIR-V compiler is part of the Vulkan SDK and may be used
by projects for compiling shaders as part of the build process.
This is not strictly required to build a Vulkan application, which
is why the variable is not part of the REQUIRED_VARs for the module.
Issue a deprecation warning on calls to `cmake_minimum_required` or
`cmake_policy` that set policies based on versions older than 2.8.12.
Note that the effective policy version includes `...<max>` treatment.
This is important in combination with commit ca24b70d31 (Export: Specify
a policy range in exported files, 2020-05-16, v3.18.0-rc1~133^2).
This fix was first made by commit 86e6349ef7 (find_program: Find
programs that are executable but not readable, 2020-04-04,
v3.18.0-rc1~372^2) but was reverted for compatibility. Re-introduce it
with a policy for compatibility.
Fixes: #10468
CPack learned the `CPACK_PRE_BUILD_SCRIPTS`, `CPACK_POST_BUILD_SCRIPTS`,
and `CPACK_PACKAGE_FILES` variables.
The first two are lists of scripts to perform
- after pre-install files into a staging directory and before
producing the resulting packages
- after produsing the packages
The post-build script(s) also get the list of actually produced
packages in the `CPACK_PACKAGE_FILES`.
Issue: #19077
The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.11 and below to encourage projects to port away
from setting policies to OLD.
The `CPACK_EXTERNAL_PACKAGE_SCRIPT` script may set this list variable to the
full paths of generated package files. CPack copy these files from the stage
directory back to the top build directory and possibly produce checksum files
if the `CPACK_PACKAGE_CHECKSUM` is set.
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.

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
