Description

When building Qt Creator with the prebuilt libclang binaries, CMake shows the following warning, and disables Clang tooling (or at least ClangFormat):

Clang build mode mismatch (debug vs release): limiting clangTooling

Checking CMakeError.log, it looks like the error is caused by bad library inclusion:

Performing C++ SOURCE FILE Test QTC_CLANG_BUILDMODE_MATCH failed with the following output:
Change Dir: F:/Projects/qt-creator/build-qtc/CMakeFiles/CMakeTmp

Run Build Command(s):D:/Utils/ninja.exe cmTC_fb07a && ninja: error: 'C:/Program Files (x86)/Microsoft Visual Studio/2019/Professional/DIA SDK/lib/amd64/diaguids.lib', needed by 'cmTC_fb07a.exe', missing and no known rule to make it


Source file was:
    #include <clang/Tooling/CommonOptionsParser.h>
    #include <clang/Tooling/Tooling.h>
    using namespace clang;
    using namespace clang::tooling;
    llvm::cl::OptionCategory CheckToolCategory("check tool options");
    int main(int argc, const char **argv)
    {
        class Parser : public CommonOptionsParser {
        public:
          Parser(int &argc, const char **argv, llvm::cl::OptionCategory &Category) :
            CommonOptionsParser(argc, argv, Category) {}
        };

        Parser OptionsParser(argc, argv, CheckToolCategory);
        ClangTool Tool(OptionsParser.getCompilations(),
                       OptionsParser.getSourcePathList());
        return 0;
    }

And indeed, C:/Program Files (x86)/Microsoft Visual Studio/2019/Professional/DIA SDK/lib/amd64/diaguids.lib appears in lib/cmake/llvm/LLVMExports.cmake:

Unable to find source-code formatter for language: cmake.

# Create imported target LLVMDebugInfoPDB
add_library(LLVMDebugInfoPDB STATIC IMPORTED)

)

Removing it seems to solve the issue, and ClangFormat builds successfully.
