No, you didn't miss anything. This isn't configurable. But you can 
easily change it by modifying the value of the OUTPUT_NAME at line 
https://github.com/OSGeo/PROJ/blob/4aa16151b98926fbbe6d8504a770379c6733ac35/src/lib_proj.cmake#L417

I suspect you could also probably override it after the fact by calling 
PROJ's CMakeLists.txt from a CMakeLists.txt of yours and doing a 
"set_target_properties(proj PROPERTIES OUTPUT_NAME "your_name")" 
afterwards, but I'm not totally sure about that.

GDAL has actually a CMake cache variable to customize this: 
GDAL_LIB_OUTPUT_NAME
