[Insight-users] Re: [CMake] Installed project with shared libs

[Zachary Pincus]

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?

PS. This might make a good FAQ entry for CMake.
