fix cxxopts and ghc cross compilation issue

While cross compiling using openembedded yocto environment,
CXXOPTS_INCLUDE and GHC_INCLUDE variables remains empty because the search
path point to the openembedded sysroot instead of the current directory.
To avoid this situation, NO_CMAKE_FIND_ROOT_PATH must be added to the
find_path call.
