The linker for my project seems to require the object file(s) as    file1.o as 
opposed to file1.c.o othewise it will not make a shared library.
I tried setting CMAKE_R_PATH as "${CMAKE_INSTALL_PREFIX}/lib" and fiddled 
around with set_target_properties()  to no avail.

So are there simple scripts that can  convert the file1.c.o ihto file1.o  or 
symlink to file1.o in  
in the ${PROJECT_BINARY_DIR}  to execute  just after compilation and before 
linking?

thanks in advance
