`cdash_coverage_collect_gcov`.  Rename `cdash` to `ctest`.

When passing a `<header>` inside a generator expression, the closing
`>` needs to be encoded as `$<ANGLE-R>`.  Add an example to the docs.

When using a custom sysroot to build things using pkg-config, some of
the output variables feature the sysroot while others do not:

```console
$ export PKG_CONFIG_SYSROOT_DIR=/path/to/sysroot
$ export PKG_CONFIG_LIBDIR=/path/to/sysroot/usr/lib/pkgconfig
$ pkg-config --cflags-only-I openssl
-I/path/to/sysroot/usr/include/
$ pkg-config --variable=includedir openssl
/usr/include
$ pkg-config --libs-only-L openssl
-L/path/to/sysroot/usr/lib
$ pkg-config --variable=libdir openssl
/usr/lib
```

When using `pkg_check_modules`, it's pretty much the same:
```cmake
pkg_check_modules(_OPENSSL QUIET openssl)
_OPENSSL_INCLUDE_DIRS == /path/to/sysroot/usr/include/
_OPENSSL_INCLUDEDIR == /usr/include
_OPENSSL_LIBRARY_DIRS == -L/path/to/sysroot/usr/lib
_OPENSSL_LIBDIR == /usr/lib
```

However, FindOpenSSL only searches for headers in `INCLUDEDIR` and
libraries in `LIBDIR` instead of searching `INCLUDE_DIRS` and
`LIBRARY_DIRS` as well.

This fixes that behaviour.

Fixes: #16885Signed-off-by: Denis Thulin <denis.thulin@enyx.fr>

Revert commit b2fd479d (FindBinUtils: Use the compiler to get the path
to compiler tools, 2019-09-22, v3.16.0-rc1~51^2).  The compiler's answer
may incorrectly come from the `PATH`.  Another approach will be needed.

aeae4182 FindPostgreSQL: support version encoding used in pre-10 releases
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !4007

With the 10.x release, PostgreSQL upstream started encoding the version
as `MMmmmm` where `M` is major and `m` is minor. Prior to that, `MMmmPP`
was used where `P` was the patch number. Detect this difference and
decode it based on the used encoding.
