This is a massive revert of the following commits (from most revent to oldest):2b9b7b5775.529ac3319728270234f169c2087283b5aa67446e5d796645d6After checking-in the __config_site change, a lot of things started breaking due to widespread reliance on various aspects of libc++'s build, notably the fact that we can include the headers from the source tree, but also reliance on various "internal" CMake variables used by the runtimes build and compiler-rt. These were unintended consequences of the change, and after two days, we still haven't restored all the bots to being green. Instead, now that I understand what specific areas this will blow up in, I should be able to chop up the patch into smaller ones that are easier to digest. See https://reviews.llvm.org/D89041 for more details on this adventure.
libc++ Documentation ==================== The libc++ documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc++ with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBCXX_INCLUDE_DOCS=ON After configuring libc++ with these options the make rule `docs-libcxx-html` should be available.
