CMake before 3.7 didn't properly pass the standard selection flags
to try_compile. Wrap try_compile on old CMake versions so that the
flag gets passed.
We're not using the <locale.h> header anywhere besides including it
for no purpose, so we can drop the test (and the inclusion).
Additionally, the header is part of standard C++.
CMake 3.5.1 is the version that ships with Ubuntu 16.04 LTS. Ubuntu
14.04 LTS was already unsupported by our build, so we don't need to
worry about that.
Debian packages older/newer gcc versions with executables named like
gcc-5, gcc-ar-5. The previous implementation did not handle this
correctly, breaking LTO-enabled linking.
When cross-compiling c4group should be build for the host
machine before building OpenClonk for the target.
Without C4GROUP_TOOL_ONLY option, we have to build OpenClonk
for the host.
C4GROUP_TOOL_ONLY allow to build only c4group tool for the
host.

With this patch I can build OpenClonk with Buildroot.
While cross-compiling, it is easier to find a binary
from the patch using FIND_PROGRAM instead of using
a cmake file.
Try to find c4group native tool with FIND_PROGRAM and
fallback to the cmake file if c4group is not found.

As reported by [1], some distributions use shared libraries as
default preset in CMake.
Without explicitely linking statically libmisc and libc4script,
we have the following link issue:

While at it, build libopenclonk statically since libopenclonk is not
installed by the CMake build system.

The crypto "library" only consists of a single function at the
moment because that's all that users have asked for so far. It is
also highly experimental. We will make an attempt to keep the public
interface (i.e. the interface provided by Library_Crypto.c) stable,
but it might still change if necessary. The internal interface
(provided via the global _Crypto proplist) is not for public
consumption and will probably change at some point.
GCC6 doesn't like getting some of its default include search paths
passed with the -isystem flag, and the devs seem unlikely to change
whatever they did back to before they broke it. Work around CMake
not dealing with it well either by figuring out the paths at
configure time and telling CMake about them so it can avoid adding
them superfluously.
The install target is used both for manual installation and for
packaging. Updating the packager's MIME cache isn't very useful. Show a
message instead which reminds both packagers and regular users to run
the command.
Scenario parameters are useful in a script-only context (such as the one
mape uses). C4AchievementGraphics introduces a dependency on C4Surface
which isn't available in that context.
MSVC already knows where the Windows SDK is located, so we don't have to
replicate that logic in CMake (then get it wrong and link to an outdated
one).
This commit introduces a new Aul directive "#warning", which can be used
to enable or disable warnings for a particular piece of code.
"#warning enable" enables all warnings.
"#warning disable" disables all warnings.
"#warning enable empty_parameter_in_call" selectively enables one
specific warning while not affecting any other.
All warnings that used to be controlled by Developer.ExtraWarnings
remain disabled by default.
Systems that don't come with getopt/getopt_long in their runtime library
need to link to our private copy; link that and use the right const-ness
for its prototype.
