Make FIND_SYSTEM_LIBRARY respect a configured sysroot, otherwise it might find headers from the build machine and assume the library is available on the host/target. Tighten up error checking: if pkg-config or the user specified _CFLAGS or _LIBS but we can't find the header/library, issue a fatal error. Fix the -L flag to /usr/local/lib instead of just /usr/local. Clean out the _CFLAGS and _LIBS if we located something that we later find doesn't work. Rename FIND_SYSTEM_LIBRARY into the ZFS_AC_ scope. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Arvind Sankar <nivedita@alum.mit.edu> Closes #10538
