Takumi,
Thank you for all the pointers, they have been quite helpful.
So, in a nutshell, it seems that both conditional checks below
can be removed:
* llvm/cmake/modules/LLVMProcessSources.cmake:45
* clang/CMakeLists.txt:295
I=92ve checked it with "Unix Makefile=94 and =93Ninja=94 generators, as both
are supported by Qt Creator.

I know about that one. As I=92ve said, I=92ve changed it and there
are seemingly no ill effects. I simply wonder if the conditional
should be permanently removed or set to TRUE, as it seems counterproductive.

This disables the progress bar for XCODE and MSVC. Probably neither
of those IDEs have the code to understand progress output, so it may
as well remain disabled. I see no reason to change it at the moment.

This is interesting. You refer here to add_clang_library.
On the surface it seems to duplicate what=92s already
present in llvm_process_sources, but it only seems so. It calls
llvm_add_library, and that calls llvm_process_sources
if no OBJLIBS argument is given. Alas, it must be that OBJLIBS are
given, and llvm_process_sources is not called since the .td and .h
files are not added unless the conditional check is removed here.
Cheers, Kuba Ober
