vcpkg_check_linkage(ONLY_DYNAMIC_LIBRARY) # Notes on Clang 7 binary download: # MDL-SDK requires Clang version 7.0.0 previsely as a *build tool* not as a *source compiler* as it is usually used. # This ports provides CMake instructions to fetch and use it to build this port - and only for this purpose: # it will not be installed and as such not be usable by any other ports. # # More details on the why below: # MDL-SDK supports its own source file format (NVIDIA MDL sources `.mdl`), and can codegen executable code at runtime using its own vendored and modified version of LLVM 7.0.0. # Also, at buildtime MDL-SDK also "pre-compile" MDL core libraries as LLVM bitcode directly into its binaries (through generated c array in headers) using this very Clang 7.0.0. # To have everything working together, we have to use a Clang as build tool which match the vendored LLVM version so that LLVM bitcode can be loaded/linked properly as it is not compatible across MLLVM versions. #
