Hi. I was trying to configure CMake to build LLVM version 10. I want to build Qt along with the Documentation which requires LLVM; I want to build Qt for WebAssembly and it detected LLVM version 10 with EMSDK, so since I want to avoid version conflicts, I thought I'd try to build LLVM version 10 myself. I tried running this command on the command line:
"cmake -DCMAKE_INSTALL_PREFIX=../install -G"Visual Studio 16 2019" -Thost=x64 -A x86 -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;lld;lldb;libcxx;libcxxabi" -DCMAKE_BUILD-TYPE=Release -MSVC_RUNTIME_TYPE=/MT -DLLVM_TARGETS_TO_BUILD=all -DLLVM_ENABLE_THREADS=On -DLLVM_CXX_STD="c++17" -DLLVM_ENABLE_PEDANTIC=On -DCMAKE_CXX_FLAGS="/std:c++17;/permissive-;/MT;/EHsc" ../llvm"
And it gave this output (please notice the errors):
"

What's the reason for this error? Could someone please help me out? And if I want to do all of this from within the IDE, how should I change the CMake settings to configure it the way I want?
Edit: I was able to start the configuration process but even though I specified this in my command line arguments: "-DMSVC_RUNTIME_TYPE=/MT", it's still using /MD instead of /MT here. I want a static build. What do I do?
Edit2: And I also want it to write all project files to C:/llvm-project/build. Is that possible?
