If on linux, assume lapack libraries are "-llapack -lblas" for CPP runtime. This needs proper portable fix but it will be done later. Removal of it caused some regressions on the CMake based testsuite test.

Define WIN32_LEAN_AND_MEAN to avoid mixup of winsock headers.

Define WIN32_LEAN_AND_MEAN on the compilation commands to avoid any chance of someone including windows.h without definning the macro and inadvertently including winsock.h which can not work with winsock2.h that we use in some places.

Fix warnings about multiple definition of OMC_HAVE_IPOPT

Define the macro in the Windows Makefile instead of the config header. It is supposed to be on always on OMDev/MinGW with the Makefiles build system

On linux with autoconf and with CMake on all platforms it can be turned
on and off depending on the availability of Fortran.

Minor fixes.

Link wsock32 to libSimulationRuntimeC instead of libOpenModelicaRuntimeC. It is not needed by the latter.

Fix compilation on OMDev/MinGW with CMake (#8976)

GC has a setting where it gets compiled as a single file (a file that includes all source files). According to the logs of the upstream GC repository this is done to enable more optimizations. It also enabled this one-file form when it was asked to build a shared library with CMake. Even if it was not asked for explicitly.

However, the markup for the functions was missing the extern keyword
which leads to some confusing duplicate declaration errors.

Add the extern specifier. But also disable the automatic one-file
compilation for shared version behavior since the autoconf build does
not enable it unless it is asked for explicitly.

We are trying to be consistent to avoid ANY surprises with this useful
(I admit) but so very intrusive and infuriating library.

Now that GC is a shared library copy the dll the directory where we generate the bootstrapped omc so that it can function.

Minor fixes for ModelicaExternalC and CPP runtime builds. (#8972)

ModelicaExternalC stand alone CMake build:
- Link to libm only on Unix.
- Export all symbols with MSVC. This is not needed right now as the stand alone build is only meant to be used for the Autoconf build system. The CMake build system has another (not the standalone) CMake file that it uses that is integrated in to the whole OpenModelica build.

CPP runtime
- Fix the install directory for CPP runtime shared libs. They want to be in the lib folder even on Windows (instead of the bin dir). The should be fixed from the other side and the libraries should be added into the bin dir together with the other DLLs OpenModelica builds.

Remove unnecessary manually set LPACK libraries string. It is not needed.

Build the garbage collector (libomcgc) as a shared library. (#8969)

The build type of omcgc with the autotools build is now changed

to a shared library on Windows. This means it is now built everywhere
as a shared lib.

The CMake build was building it as a static library on all platforms
to be consistent. Change it to shared lib now so we now, under both
build systems and on all platforms, build omcgc as a shared library.

Build libOpenModelicaRuntimeC and libomcgc as DLLs. (#8961)

We now build both of these libs as dlls on Windows. They are already built as shared libraries on linux.

We build libomcgc as shared library because we do not want to ever have
two instances of the garbage collector linked into one binary (exe or dll)
ever. Having two instances of the garbage collector leads to quite
ominous bugs that would be vey difficult to find. See #8738 and #8955
Just avoid the possibility altogether.

We build libOpenModelicaRuntimeC as a dll because it saves memory.
It is linked to every simulation executable we generate and there is
no reason to duplicate it in every one of those executables. We will
see what implications this will have for FMUs.

Fixes #8738.
