I want to start using clang and clang++ but have a few questions:
1. Has anyone a working, general solution for driving a CMake-built
project with clang or clang++ (using build directories not polluted by
gcc/g++ attempts)?
2. Are clang- and clang++-built libraries and programs
interchangeable with gcc- and g++-built libraries and programs?
3. Are clang- and clang++-built libraries and programs usable on
another Linux host (same distro, both 64-bit) without LLVM installed?

Yes. GCC and Clang implement the same ABI, any issues here is a bug either
in GCC or in Clang.

another Linux host (same distro, both 64-bit) without LLVM installed?
Yes. Clang built binaries don't inherently rely on llvm.
Not sure what you mean exactly... sounds like more of a CMake question, but if I understand you correctly, you just need to tell cmake which compiler to use, ex:
$ cd bin-dir
$ CC=clang CXX=clang++ ccmake /path/to/src
