error: cannot find -lXpm. But libXpm is in /usr/lib

Hi
When I compiler ncl with icc and ifort, it always appear the error: "cannot
find -lXpm". Such like:

ifort -O2 -o tdpackdemo TdpackDemo.o
-L../../../.././ncarg2d/src/libncarg -lncarg
-L../../../.././ncarg2d/src/libncarg_gks -lncarg_gks
-L../../../.././common/src/libncarg_c -lncarg_c -lpng -lz
 -L/mnt/home/xqiu/Program/IntelCompiled/Ncl_ncarg-5.1.1/lib -L/usr/lib
-L/usr/lib/X11 -L/mnt/home/xqiu/Program/IntelCompiled/lib -lXpm -lX11
-lXext
ld: cannot find -lXpm

But the libXpm is in /usr/lib
/usr/lib/libXpm.so.4
/usr/lib/libXpm.so.4.11.0

I don't know why it can't be found by the compiler? Does anyone know it?
Thanks!
