-lfoo vs /usr/local/lib/libfoo.so

In trying to build a dev version of a port, the cmake script includes
many libraries explicitly, and one (-lhdf5-18) using -l:
/usr/bin/c++ -fPIC -Wall -Wextra -Wno-write-strings -O2 -pipe
-I/usr/local/include/hdf5-18 -fstack-protector -isystem /usr/local/include
-fno-strict-aliasing -isystem /usr/local/include -std=c++11
-Wno-undefined-var-template -D_OCC64 -O2 -pipe -I/usr/local/include/hdf5-18
-fstack-protector -isystem /usr/local/include -fno-strict-aliasing -isystem
/usr/local/include -Wl,--no-undefined -shared
-Wl,-soname,libFreeCADBase.so -o ../../lib/libFreeCADBase.so
... a bunch of .o files ...
... <more .so files> ...
-lpthread -lz /usr/local/lib/qt4/libQtCore.so
The above command fails with
"/usr/bin/ld: cannot find -lhdf5-18"
exists and the rpath flag indicates /usr/local/lib
If I replace -lhdf5-18 with /usr/local/lib/libhdf5-18.so it works.
Curiously (to me) -lpthread and -lz are apparently working correctly,
or at least aren't being mis-interpreted.
I've tried tweaking the command to use -Wl,-lhdf5-18 but that fails also.
Can anyone explain to me what's going on?
