Thanks for testing it.

That script causes CMake to be configured with itself the second time
instead of the bootstrap script.  You should be able to pass the config
options directly to bootstrap:

  ../cmake-3.6.0-rc1/bootstrap --parallel=${NPROC} -- \
    -DCMAKE_BUILD_TYPE:STRING=Release \
    -DCMAKE_USE_OPENSSL:BOOL=ON \
    -DOPENSSL_ROOT_DIR:PATH=/usr/local/ssl &&
  make -j ${NPROC} &&
  make install

This should fix it:

 libarchive: Restore OpenSSL include directory from upstream
 https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=dbc9f73d

I've queued this for merge to 'release' for 3.6.0-rc2.
