I tried to check out libc++ into llvm/projects/libcxx and invoking
configure again. This message during configure gives me pause though:
configure: WARNING: Unknown project (libcxx) won't be configured
Even passing --enable-libcpp to configure does not get rid of this
warning. In fact, the Makefile in llvm/projects mentions:
# Don't build libcxx, it isn't designed to be built directly.
DIRS := $(filter-out libcxx,$(DIRS))
Should clang pick up libc++ automatically or am I supposed to install it
