Build script can not find '-laec' when libaec is installed in non-default directory

[DusanJovic-NOAA]

The compilation fails with this error:

[ 96%] Built target obj_lib
[ 97%] Linking C executable wgrib2
/opt/rh/gcc-toolset-12/root/usr/libexec/gcc/x86_64-redhat-linux/12/ld: cannot find -laec: No such file or directory

I have libaec (and all other 3rdparty libraries) installed in a local directory, and I specified that location with -DCMAKE_PREFIX_PATH.

The location of aec library in wgrib2/CMakeLists.txt should be specified using LIBAEC_LIBRARIES variable instead of aec string.
