According to the documentation, applications using SHFileOperation
should only check for zero or non-zero. Moreover, the return values for
SHFileOperation are marked as not reliable or stable. [1]
Because of this, it is not possible to achieve the same behaviour
between Win32 and POSIX for portability::rmdir_r.

Otherwise, libraries built by the xmlversion target (namely,
portability, tgf and txml) could be built under a different
CMAKE_BUILD_TYPE.
For example, if CMAKE_BUILD_TYPE were assigned to Debug from the
top-level project, these libraries would otherwise under Release and
therefore debugging symbols would not be available.

Windows and POSIX had different behaviours for portability::rmdir_r if
a directory did not exist. This commit therefore modifies the Windows
implementation so as to match the same behaviour as in POSIX, and
therefore recover the original implementation in main.cpp.
This reverts commit r9624.

on Windows it returns non-zero since SHFileOperation fails in such
circumstances.

- Fixes for excessive tire wear when cars spawn with wheels below the ground by limiting
- Ability to tweak tire temperature gain depending on 2D axis direction ("lateral mu heat factor" or "longitudinal mu heat factor")
- Ability to tweak tire cool down rates ("tire cooling factor", "tire speed cooling factor")
- Ability to tweak tire's ability to maintain heat in wet conditions ("tread water drain speed" - defaults to 0 for dry tires, 1.5 and 3 for and inter/wet tires). Higher numbers mean tires can retain heat even when track is wet.
- Removed explicit penalties for tire grip and heating for using wet tires on dry track
In addition, "Stiffness" now changes in accordance to tire pressure. This is intended to simulate the tire becoming stiffer as tire temperature - and thus - pressure - increases.
Unfortunately this breaks the parameters for A LOT of cars in some way: cars without tire options will be undrivable in wet conditions by default, and tire compounds must be rebalanced for cars with them.

Even if GFPARM_RMODE_REREAD was meant as an optional flag for
GfParmReadFile, it is always set by the implementation. This forced
the parameter file to be always opened for reading, which would fail if
the file did not exist. This is undesired when creating new parameter
files from scratch.
Since this behaviour is probably assumed by many parts of the code, a
new flag, namely GFPARM_RMODE_NOREREAD, has been added so as to disable
such behaviour while maintaining backwards compatibility.

The previous implementation naively assumed that, prior to extracting
a file from a .zip, its parent directory would appear earlier on the
list and, therefore, the directory would be created beforehand.
This naive assumption made the extraction to fail when valid .zip files
listed files before their respective directories.

CMake discourages the use of configure_file() to generate files such as
cJSONConfig.cmake because it might expand variables such as
<project>_INCLUDE_DIR to absolute paths, which might cause issues on
Windows and macOS [1].
Instead, configure_package_config_file() is meant as a drop-in
replacement that generates cJSONConfig.cmake using relative paths. In
the context of this project, this should allow pre-compiled versions of
the `3rdParty` directory to be shared among developers.

MinGW already distributes OpenGL headers and libraries under different
directories. In such cases, it is more sensible to rely on those than
the in-tree copies maintained by the project.
Note that, for some unknown reason, the include directories for the
OpenGL::GL target are not filled, even if find_package(OpenGL) is
successful and the library is found. Therefore, this commit works around
this limitation by finding GL/gl.h from a possible list of directories
inside the toolchain.

If the user configures the project with a CMAKE_PREFIX_PATH, subprojects
such as xmlversion would not be configured correctly because its
CMAKE_ARGS would expand -DCMAKE_PREFIX_PATH to:
${PROJECT_SOURCE_DIR}/3rdParty ${CMAKE_PREFIX_PATH}
And this whitespace-separated list would be refused when configuring
xmlversion.
This has one side effect: the user is now required to always assign
CMAKE_PREFIX_PATH when configuring the project, and therefore not rely
on the 3rdParty directory to be available from the root directory.

These libraries must be installed into the bin/ directory in order to
run the speed-dreams-2 executable.
Note that MinGW is distributed with several flavours and therefore might
define different names for libgcc. [1] libstdc++-6.dll has also been
found on different directories depending on the flavour. On the other
hand, libssp might not be available on some distributions, so it remains
optional.

xmlversion is meant to be a build-time tool, which means it must never
be cross-compiled. Since toolchain settings are shared among all
libraries within a project, the only way in CMake to build an executable
using the host toolchain (instead of the cross-toolchain) is to define
it inside of an ExternalProject.
xmlversion also depends on several in-house libraries that must be also
build with the host toolchain, so those libraries shall be both
cross-compiled and natively compiled.
On the other hand, since a known install prefix is assigned to
xmlversion, _XMLVER_EXE, _XMLVER_DIR and _XMLVER_NAME no longer need to
be calculated.
Note that CMAKE_FIND_ROOT_PATH must not be passed to the ExternalProject
since xmlversion must never be cross-compiled.

ADD_INTERFACE_INCLUDEDIR relied on legacy CMake macros such as
INCLUDE_DIRECTORIES. Nowadays, targets do not specify their
dependencies' include directories, but just call target_link_libraries
so that CMake takes care of the rest.

directories, if any, via target_include_directories.

However, the same effect can be achieved via the standard CMake

When calling find_package(CURL), different files might be inspected:
- $CMAKE_PREFIX/Modules/FindCURL.cmake
- 3rdParty/lib/cmake/CURL/CURLConfig.cmake
Which file is selected is decided by CMake depending on the context.
Unfortunately, whereas the former defines CURL_LIBRARY, the latter
does not.
However, both define the CURL::libcurl target, from which the library
location can be retrieved with get_property() so as to achieve the
same effect.
Fixing this also makes CURL_NO_CURL_CMAKE redundant.

There were several errors when building OpenSceneGraph for Windows:
- using namespace std caused ambiguity with some symbols, and
DisplaySettings.cpp was already prepending std:: to all standard
symbols.
- ChangeDisplaySettingsEx returns a LONG [1], so casting to unsigned int
causes loss of precisions in some platforms.

Future commits shall patch these files to fix some build-time issues in
Windows. Since CMake lacks a PATCH command as of the time of this
writing, files must be copied entirely.

There are several errors when building plib for Windows:
- Casting a pointer to DWORD is unsafe because they might have different
sizes. DWORD_PTR [1] must be used instead.
- Casting a pointer to long is unsafe because they might have different
sizes. ptrdiff_t must be used for pointer arithmetic.
- slDSP::counter is private so it cannot be used by waveOutProc. A
public function is now defined to achieve the expected behaviour.
