Qt Tools:
  QDoc ................................... noNote: Also available for Linux: linux-clang linux-iccNote: Using static linking will disable the use of dynamically
loaded plugins. Make sure to import all needed static plugins,
or compile needed modules into the library.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.Qt is now configured for building. Just run 'gmake'.
Once everything is built, you must run 'gmake install'.
Qt will be installed into '/usr/local/Qt-5.15.2-static'.Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
