# NOTE: It seems that there's no (sane) way how to change includedir, sharedir
# etc. separately, just the CMAKE_INSTALL_PREFIX. Standard CMake variables and
# even  LLVM-specific variables, that are related to these paths, actually
# don't work (in llvm 3.7).
#
# When building a software that depends on LLVM, utility llvm-config should be
# used to discover where is LLVM installed. It provides options to print
# path of bindir, includedir, and libdir separately, but in its source, all
# these paths are actually hard-coded against INSTALL_PREFIX. We can patch it
# and move paths manually, but I'm really not sure what it may break...
#
# Also note that we should *not* add version suffix to files in llvm bindir!
# It breaks build system of some software that depends on LLVM, because they
# don't expect these files to have a sufix.
#
# So, we install all the LLVM files into /usr/lib/llvm$_majorver.
# BTW, Fedora and Debian do the same thing.
