Cross Compile and losing libraries

I have the following system for cross compilation: a computer on which I build, on which the file system of the target computer is mounted. So, I do the compile and everything, no problem, pointing to the libraries I need (I compile with OpenSSL) by their location on the compilation computer. When I switch to the target computer, the libs are there, but of course on a different path, and PHP doesn't want to run, pointing to unable to find the libs. It doesn't help to put them in the PATH. PHP won't run unless I create for them a PATH exactly like it was on the compilation computer. Any idea? There must be a simple way to solve it that I dont't know. Oh, and, of course, I don't want to compile with static libraries as it's a waste of dear space. Thanks.
