Disable building of shared libraries with LLVM and MinGW so that remaining __declspec macros needed for the functional libraries built by MSVC can be used without triggering errors in LLVM and MinGW builds. For Windows only install the default_library type to avoid confusion. Windows builds cannot build both shared and static in a single pass so install only the functional variant MSVC does not guarantee any kind of compatibility for static libraries so they should not be packaged and instead they should be rebuilt along with the application using the same version of the compiler & linker. Because of this we have chosen to build only one library type at a time instead of compiling twice to produce both types in a single pass. thanks Bruce for all the discussion/feedback! v5: set RTE_BUILD_SHARED_LIB in a single location when building with msvc and is_shared_enabled instead of scattered over various meson.build files. v4: * use add_project_link_arguments() and move addition of linker and compiler arguments required only dynamic linking to block where it is determined is_shared_enabled=true and don't specify when is_shared_enabled=false. * unconditionally initialize shared_deps = {} and get rid of else leg of conditional evaluation in drivers/meson.build and lib/meson.build. * drop change to octeontx meson.build. v3: * condense library, target and toolchain type logic determining values for is_shared_enabled,install_{static,shared} values. * define empty shared_dep object to allow unconditional evaluation of shared variables even when is_shared_enabled is false. * use default_library() string to determine deps for chkincs.
