The Ninja generator traditionally referenced source files and include
directories using paths relative to the build directory if they could be
expressed without a `../` sequence that leaves the build and source
directories. For example, when using a `build/` directory inside the
source tree, sources would be compiled as `-c ../src.c` and include
directories would be referenced as `-I ../include`. This approach
matches the traditional Ninja convention of using relative paths
whenever possible, but has undesirable side effects such as:
* Compiler diagnostic messages may not use absolute paths, making it
harder for IDEs/editors to find the referenced sources or headers.
* Debug symbols may not use absolute paths, making it harder for
debuggers to find the referenced sources or headers.
* Different results depending on the path to the build tree relative
to the source tree.
* Inconsistent with the Makefile generators, which use absolute paths.
Switch to always using absolute paths to reference source files and
include directories on compiler command lines. While alternative
solutions for diagnostic messages and debug symbols may exist with
specific tooling, this is the simplest and most consistent approach.
Note that a previous attempt to do this in commit 955c2a630a (Ninja: Use
full path for all source files, 2016-08-05, v3.7.0-rc1~275^2) was
reverted by commit 666ad1df2d (Revert "Ninja: Use full path for all
source files", 2017-02-24, v3.8.0-rc2~9^2) due to problems hooking up
depfile dependencies on generated files. This time, the changes in
commit 2725ecff38 (Ninja: Handle depfiles with absolute paths to
generated files, 2021-05-19) should avoid those problems.

The `Vulkan::Headers` target complements existing Vulkan::Vulkan target.
It is the same except it omits the Vulkan library which supports
applications that loads the Vulkan library in at runtime.
The `Vulkan::glslangValidator` target provides the glslangValidator
executable which is the tool for converting between shader languages
(GLSL, SPIR-V, etc.).
The new variable allows projects to define custom key=value pairs of
variables to be set in CPack cmake_install.cmake script invocations.
This allows install(SCRIPT|CODE) to be parameterized at runtime.

In a per-component installation the generated installation scripts
are invoked once for each component.
Per default custom installation script code added by install(CODE|SCRIPT)
only runs for one specific component in this context.
The new ALL_COMPONENTS option allows custom script code to be run once
for each component being installed.
Comments at the bottom of the docs for add_compile_options() and
target_compile_options() recommend using other commands if setting
compiler definitions. Change the examples we use for the SHELL:
functionality to use -option instead of -D so that we don't violate our
own recommendations. This also makes the examples more
appropriate for use with link options as well.
Tweak the wording to not specify the type of option being discussed.
This will already be clear from the page the text is included into and
it avoids naming unrelated option types for the given page.
These fields are specified by our `P1689r3` paper, but are not actually
needed. The dependencies of the scanning results themselves can be
captured via normal depfile logic. Avoid saving this possibly-large
information in the scanning results. It is not needed by later steps.
add_jar() currently requires (undocumented) that resources be supplied
as relative paths. The resources *may* then end up in a path which does
not reflect the original path particularly when performing out-of-source
builds. This change adds a RESOURCE (and NAMESPACE) parameter and a
function to add the names resources into the named namespace within the
jar- and thus address both of these problems.
