During the build of Qt 5.14.1 I've just spotted the following in the log:
Qt Tools:
QDoc ................................... no
WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.
Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.
I assume nobody needs that, right? Otherwise one might add mingw64-llvm
as dependency but I don't think it is worth it (these packages need long enough to build anyways and are error prone enough).
