1. Set CMAKE_FIND_ROOT_PATH unconditionally.
Revise the implementation from commit a7f41a7ee4 (Android: Fix find_*
search order within NDK for unified toolchains, 2020-10-13). In the old
implementation, if people set CMAKE_FIND_ROOT_PATH, CMAKE_ANDROID_NDK
won't be added to find root. And all paths added to CMAKE_SYSTEM_*_PATH
below will be rerooted to the user specified root.
2. Add api level specific library path to CMAKE_SYSTEM_PREFIX_PATH.
As the discussion in [1], some people want the paths added by
UnixPaths.cmake. They install their libraries according to
GNUInstallDirs [2].
As a result, we cannot clear CMAKE_SYSTEM_PREFIX_PATH. It includes /usr
so no matter what we specify in CMAKE_SYSTEM_LIBRARY_PATH,
/usr/lib/<arch> will be searched first.
The author also pointed out a way to solve this issue [3]. In addition
to other paths, CMake also searches <root>/<prefix> [4]. So we can add
the API specific lib path to the beginning of CMAKE_SYSTEM_PREFIX_PATH,
to have it searched first.

Extend the `.tbd` parsing from commit 170e598add (iOS: Fix detection of
supported SDK architectures, 2020-04-16, v3.17.2~11^2) to support `.tbd`
file version 4.

This fixes the following two issues with the CUDA support on QNX:
* cuda target name is not derived correctly (should be `aarch64-qnx`).
* linking `cudart` must not be linked against `rt`, `dl`, `pthread`.
This enables to use cmake's native cuda support on QNX.
Fixes: #21381
* Add "ICU_" suffix to all _FOUND variables
* Ensure cache variables can also be used with correct
ICU_ suffix and compatibility name
* Improve ICU_DEBUG messages to verify compatibility and
corrected variable names are set to the correct values
Since commit 4b2a61946f (FindBoost: Honor BOOST_ROOT when finding
upstream BoostConfig, 2020-10-22, v3.19.0-rc2~14^2) we accidentally leak
our internal setting of `Boost_ROOT`. Revise the logic to unset our
temporary value.
Fixes: #21379
The old `check_X_source_runs` modules did not verify the arguments, so
we cannot start doing it now. Downgrade the hard error introduced in
commit 357e2ef429 (CheckSoureRuns: Add a unified way to check if a
source runs, 2020-09-14) via !5223 into a noisy warning.
Since commit e672db628b (FindRuby: Rename variables to match case of
module name, 2020-03-11, v3.18.0-rc1~546^2), the result variables named
with the old `RUBY_` prefix are provided by compatibility code that maps
from the new `Ruby_` prefix variables. This variable was accidentally
left out.
Fixes: #21369
The conversion of Check<Lang>CompilerFlag, SourceCompiles, and
SourceRuns over to the new functions has the possibility of breaking
projects that had functions with those existing names.
To reduce the possibility of collisions we now have all the
legacy code call functions that start with `cmake_`, and users
will need to explicitly include the new modules to get the
non-prefixed versions
Fixes: #21359
