Thanks everyone for your suggestions about how to deal with rpaths
(aka install names for OS X dylibs) and installed shared libraries.
Option A is to disable the rpaths and make sure that (1) the
libraries are installed in a "standard" location, or (2) [DY]
LD_LIBRARY_PATH is set to the installed location. This is possible in
any version of CMake with CMAKE_SKIP_RPATH.
Option B is to link two libraries: one for the installed location and
one for the build tree location. This is possible with CVS CMake,
thanks to Brad's changes.
My questions are now three:
(1) Do you think that A or B is a better solution, in the unix-like
OS case?
(2) Do either of these solutions have equivalents on Windows
machines? Or is the dynamic linker there sufficiently different? If I
want to get something working cross-platform, it would be helpful to
know what to have to do.
(3) Does anyone know if ITK is moving toward a solution for the
problem of rpaths in installed shared libs? And if so, what is that
solution?
Zach
PS. This might make a good FAQ entry for CMake.
