The `/GR` flag has been on by default since MSVC cl 14.0 from VS 2005.
Remove it from the default flags to make it easier for projects to pass
`/GR-` themselves to turn it off.
Projects may be using string processing to replace `/GR` with another
flag, so we cannot simply drop it. Add a policy to drop it in a
compatible way.
Fixes: #21428
When targeting a platform that supports multiple architectures, Xcode
may choose to build all of them in our small compiler id project.
Update the regex we use to extract the path to the compiler from
the Xcode output to account for this.
Fixes: #21425
In commit b6c60f14b6 (macOS: Default to arm64 architecture on Apple
Silicon hosts, 2020-09-28, v3.19.0-rc1~63^2) we forgot to update the
compiler id architecture selection added by commit 26673bf480 (Xcode:
Explicitly specify default native architecture on macOS, 2020-07-16,
v3.18.1~20^2).
Issue: #21425
Revise logic from commit 1ab574a0f4 (Android: Add support for NDK r22,
2020-10-07, v3.19.0-rc1~18^2) that loads ABI tables from the NDK.
`NDK_DEFAULT_ABIS` means the abis to build by default.
Use `NDK_KNOWN_DEVICE_ABI{32,64}S` instead.
In practise they have never been different. Fix to make it more precise.
Policy CMP0056 determines whether `CMAKE_EXE_LINKER_FLAGS` are passed
into the test project used by the source-file signature of `try_compile`.
That affects how implicit link directories are detected, so we need to
also honor the policy for the source-directory signature of `try_compile`
used in FortranCInterface in order to get matching link directories.
Fixes: #21408
Extend the change from commit 23cd98a66a (FindPython: Add support of
version 3.10, 2020-10-16, v3.19.0-rc2~25^2) to cover the legacy
`FindPython{Interp,Libs}` modules too.
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.
