set CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH based on NIX_CFLAGS_COMPILE and
NIX_LDFLAGS so that cmake's find_library like functions find all the libraries
gcc knows about thanks to the gcc wrapper
This is particular useful with myEnvFun which then also sets those CMAKE_* env
variables.`
Because setup.sh has to change this causes many rebuilds - thus it should be
included in a stdenv-update like branch
Also cmake builds in parallel perfectly fine
update cmake to latest minor number, I didn't change the patches,
just reapplied them manually recordin a new patch
looking in /usr and similar locations. However, it *will* now look
in the Nixpkgs Glibc lib and include directories. This ensures that
find_library can find libraries in Glibc.
