CFLAGS is added to the linker flags and newer LLVM don't like that.
CPPFLAGS is used during C compilation and C++ but not added to LDFLAGS.

newer clang reports that it ignores the command on each C++ file compiled.
In the end the static C++ compiler is used on Windows anyway.

This avoids potential compiler optimizations when casting to void** when using
IID_PPV_ARGS or WRL.

If the option is not supported we fail the configure as many important C++
modules may not work as expected due to pointer aliasing. In practice this
should never happen as GCC for mingw-w64 and Clang support this correctly.

Maybe it was OK to keep it in 3.0 but in 4.0 we can't expect to reuse ancient
folders, just to save a luac rebuild.

Also add a nice message when configuring.

Detection only worked on Linux, but more importantly, this flag fell out of
use with 8512cab6.

Same problem as 0c482e07.

This was added over a decade ago, but ...

This is necessary for Linux-specific getauxval() and associated flags.
In this case, VLC needs AT_HWCAP (and probably AT_HWCAP2 going forward)
to detect CPU features on most architectures.

This requires MacOS 10.5 or less, which was dropped in VLC 2.1.0.

This follows the established cargo cult of not assuming that the
toolchain supports SIMD.

Allow the configure script to substitute the theme used in the
documentation for Awesome doxygen css from the CI script.

The theme won't be mandatory, but we can change it and inject it for the
production documentation online.

Otherwise it won't compile compatible code.

If protoc is not there we check the version of protobuf we expect so we get the
proper error messages on what's really missing.

Similar to how we force detection of luac there.

We might be using
AC_CHECK_TOOL(PROTOC, protoc, no, [${CONTRIB_DIR}/../bin$PATH_SEPARATOR$PATH])

Which works, but it doesn't keep the full path, so if the PATH is not set in
the environment when using HOST-protoc it doesn't find it. So we either have to
force everyone to add a new item in their PATH or just use the transparent way
that luac is using.

Similar to how we use $host-luac that we build natively.

Traditionally the presence of the header file was not considered
sufficient, though this was somewhat forgotten with the prevalence of
pkg-config.

However most libraries have portable headers, while the shared library
is platform-dependent. It is common for the header to be present while
the library is absent with "multilib" installations (i.e. Linux
installation with multiple architectures).

It avoids using autoconf conditionals and defining -rpath manually, and
makes HAVE_KMS available in the Makefile.am.

The AX_APPEND_FLAG arguments were reversed, the program was not escaped
from m4 macros, and the function was declared in the body of the main
function, so it just couldn't work.

After fixing this, static module bank is back working normally on
MacOSX.

DeckLinkAPIDispatch.cpp is not available on Windows.

DeckLinkAPI.h is available on all supported platforms.
