For policy-specific tests, use the version before the policy was
introduced. Otherwise, use 3.5 where possible.
Also, remove `cmake_minimum_required()` and `project()` calls from
individual cases where they are handled by `CMakeLists.txt`.
The RunCMake infrastructure's `*-stdout.txt` expected output files
interpret `\n` as a `\` and `n` rather than a newline. Use a literal
newline instead. Otherwise the cases that were trying to match any
configuration name via `[^\n]*` would fail on `RelWithDebInfo` because
it contains the letter `n`.
The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.14 and below to encourage projects to port
away from setting policies to OLD.
The "all" target defined for a subdirectory (e.g. `cd sub; make` or
`ninja sub/all`) should not include the "all" targets from nested
subdirectories (e.g. `sub/sub`) that are marked as `EXCLUDE_FROM_ALL`.
Fix this and add a test case.
Issue: #19753
Co-Author: Sebastian Holtermann <sebholt@xwmw.org>
The "all" target in each directory is supposed to have targets from that
directory even if the directory itself is marked `EXCLUDE_FROM_ALL` in
its parent. This was broken by commit dc6888573d (Pass EXCLUDE_FROM_ALL
from directory to targets, 2019-01-15, v3.14.0-rc1~83^2) which made the
participation of a target in "all" independent of context. Revert much
of the logic change from that commit to restore the old behavior. Then
re-implement the behavior intended by the commit to keep its test
working. Extend the test to cover the old behavior too.
Fixes: #19753
When a target is created it now inherits the EXCLUDE_FROM_ALL property
from its directory. This change makes it possible to include a target
in "all", even if its directory has been marked as EXCLUDE_FROM_ALL.
Refactoring in commit v3.3.0-rc1~76^2 (cmMakefile: Handle CMP0014 before
configuring the generator, 2015-05-14) accidentally left the file name
"/CMakeLists.txt" in the error message. Remove it and add a test case.
