The fix in commit 5117389931 (VS: Fix support for v142 toolset minor
versions, 2019-10-01, v3.16.0-rc1~32^2) worked around a bug in VS's
placement of toolset files. VS 16.5 will fix that bug and restore the
original pattern for locations of toolset files. Update our logic to
look for both possibilities.
Issue: #19779
When using ThreadSanitizer our existing CMAKE_HAVE_LIBC_PTHREAD test
program links using symbols from the tsan library. Among the symbols
not provided by that library, `pthread_cancel()` seems to be the less
risky symbol to add to the check.

At CPack running time the `CMAKE_PROJECT_HOMEPAGE_URL` variable
is not set.
Internal CPack modules (e.g. CPackDEB, CPackRPM, CPackFreeBSD)
should use `CPACK_PACKAGE_HOMEPAGE_URL` instead, which is available
after inclusion of `CPack.cmake` into `CMakeLists.txt`.

This makes it much easier to use a launcher for all CMake projects in an
environment rather than having to remember to pass the setting to every
CMake build.
Revert commit de5f123d3a (FindThreads: Do not hard-code '-l' flag on
library name, 2019-09-23, v3.16.0-rc1~71^2). Some clients depend
on the value of `CMAKE_THREAD_LIBS_INIT` to contain a valid flag.
Fixes: #20061, #20065
When cross compiling from a unix machine, if(UNIX) is false,
whih causes the path not to be fixed for unix, leading to false
negative if PKG_CONFIG_PATH needs to be probed
Starting with CUDA 10.2 the nvcc compiler has gained support
to automatically forward unknown flags to the host compiler.
This behavior is highly desired as projcts that mix CUDA, C, C++
run into situation where flags such as `-pthread` which aren't
supported by nvcc, are being applied to all source files and
therefore break CUDA compilation.
We search for tools `ninja-build`, `ninja`, and `samu` as the build tool
for the Ninja generator. Re-order the search to prefer whichever tool
appears first in the `PATH`. This makes it easier for users to control
which tool gets used when more than one is available.
Fixes: #20028
