Allow `cmGlobalGenerator`s to decide `HasKnownObjectFileLocation()` per given
`cmTarget`
- `cmGlobalGenerator::HasKnownObjectFileLocation()` now takes an optional `cmGeneratorTarget`
- `cmTarget::HasKnownObjectFileLocation()` added as a shorthand

Previously items linked via the link interface of a dependency were
reported in CMP0028 messages as if directly linked by a target.
Clarify the messages to indicate that an offending item is actually
in the link interface of a given target, regardless of its consumer.
Move the check to the end of generation and look through the final set
of link implementations and link interfaces that were used for
generation. This avoids repeating messages on link interfaces that
have multiple consumers.

Revert the changes from commit d5b5c19278 (cmGlobalGenerator:
FindMakeProgram() before CMakeDetermineSystem, 2020-06-15,
v3.19.0-rc1~619^2~3) and commit ef91fb02f3 (cmGlobalGenerator:
FindMakeProgram() at a generator-specific time, 2020-11-23,
v3.19.1~2^2). We must delay selecting the location of MSBuild until
after an instance of Visual Studio has been selected.
It is now safe to revert the ordering because the motivating use
case (sysroot detection in Platform/Android-Determine) has been
implemented another way.

CMake uses explicit 'this->' style. Using custom clang-tidy check we can
detect and fix places where 'this->' was missed.

* Adding implementation for policy CMP0118 being set to `NEW`.
* Adding new tests for policy CMP0118 being set to `NEW`.
* Checking the `GENERATED` property with `get_source_file_property` or
`get_property` now always returns exactly `1` or `0`. No other values
will be returned. Note, that this is a backwards-incompatible change,
even when policy CMP0118 is unset or set to `OLD`.
* Additionally, as `get_source_file_property` and `get_property` now
always check if a source-file was marked globally visible, even when
CMP0118 is unset or set to `OLD`, they possibly return `1` where they
might have returned `0` before the changes introduced by this commit.
Note, that this is a backwards-incompatible change, even when policy
CMP0118 is unset or set to `OLD`.
* As a consequence, the tests for policy CMP0118 being unset or set to
`OLD` got slightly adjusted, too, to reflect these changes in
behavior.

ef91fb02f3 cmGlobalGenerator: FindMakeProgram() at a generator-specific time

d5b5c192 moved FindMakeProgram() to an earlier time, which resulted
in CMAKE_MAKE_PROGRAM not being read from the toolchain file. Change
it to only call FindMakeProgram() early in the specific cases of
Visual Studio and Xcode, and restore the old behavior for all other
generators.

#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.

This allows for setting EXCLUDE_FROM_ALL, conditional on the build
configuration. However, only the Ninja Multi-Config generator supports
different property values per config. All other multi-config
generators will yield an error in that situation.

Adds a flag to indicate that pipe output from a custom command should be
interpreted as UTF-8 encoded. This change does not introduce a public
way to set the flag, but generators that create internally-generated
commands know if they are calling cmake, which uses UTF-8 pipes.
MSBuild added support for interpreting output of PreBuildEvent,
PreLinkEvent, PostBuildEvent, and CustomBuildStep as UTF-8. This change
will appear in Visual Studio 16.6 Preview 3. It is opt-in, and you need
to add the StdOutEncoding tag. MSBuild treats these as property bags so
if we emit the tag for earlier versions of Visual Studio it would be
safely ignored. This change emits the StdOutEncoding tag and sets it to
UTF-8 whenever the custom command UTF-8 pipe flag is set. This fixes
globalization issues when the output from cmake contained characters
that required MSBuild to interpret as UTF-8 before displaying them.

CMake 3.16 and below allow multiple `export()` calls with the same output
file even without using `APPEND`. The implementation worked by accident
by leaking memory. Refactoring in commit 5444a8095d (cmGlobalGenerator:
modernize memrory managemenbt, 2019-12-29, v3.17.0-rc1~239^2) cleaned up
that memory leak and converted it to a use-after-free instead.
The problem is caused by using the `cmGlobalGenerator::BuildExportSets`
map to own `cmExportBuildFileGenerator` instances. It can own only
one instance per output FILE name at a time, so repeating use of the
same file now frees the old `cmExportBuildFileGenerator` instance
and leaves the pointer in the `cmMakefile::ExportBuildFileGenerators`
vector dangling. Move ownership of the instances into `cmMakefile`'s
vector since its entries are not replaced on a repeat output FILE.
In future work we should introduce a policy to error out on this case.
For now simply fix the use-after-free to restore CMake <= 3.16 behavior.

We may want to enable these variables later on with specific
semantics. To avoid breaking backwards compatibility, make it an
error to use them for now.
|
|
|
|
| |
And give other generators a path forward to add support in the future.
|
|
|
|
| |
And allow them to read any cache values they need.

Since commit b80557c7bd (file(GENERATE): Evaluate early to allow
generating source files, 2014-11-04, v3.2.0-rc1~398^2) we create the
`cmSourceFile` instances marked with a `GENERATED` source file property
before tracing source dependencies. Move it to even earlier so that
steps in `cmGlobalGenerator::AddAutomaticSources` can operate on all
sources. This also avoids the accidental `O(n^2)` calls for `n` local
generators that we had previously.
This is also needed since commit 83c1657ff7 (Unity build: Generate
sources during Compute step, 2019-10-03) to support `file(GENERATE)`
outputs as sources in a target with `UNITY_BUILD` enabled.
|
|
|
|
|
|
|
|
| |
The unity build sources need to be added for all generators. Create
them during `cmGlobalGenerator::Compute` to avoid duplicating the calls
in every generator. We already handle Qt autogen there too.
