[ODE] Problems installing ODE libraries under cygwin

[Maurice Hüllein]

For compiling a project which needs the ODE library under Cygwin I 
downloaded the suitable
binaries from the project's homepage.
As the archive already includes cygwin-binaries with headers and and a 
configured user_settings
file I proceeded to the step where the files are copied into the file 
system of cygwin:

*Step 5:* To install the ODE library onto your system you should copy 
the lib/ and include/ directories to a suitable place, e.g. on Unix:

   * include/ode/ --> /usr/local/include/ode/
   * lib/libode.a --> /usr/local/lib/libode.a


The problem is, that making the desired project it complains about the 
missing ODE libraries.
I had a similar problem installing another library (expat), where 
copying the files got no result
while installing via cygwin-setup was successfull. So as a guy not 
knowing too much about cygwin:
is there any additional step (registering the lib or setting any 
environment variable) to do?
