Comment(by hvdwolf@…):

 I do not exactly understand what you mean. The relevant part in the
 CMakeLists.txt file is:
     IF (CMAKE_INSTALL_PREFIX STREQUAL "/opt/local")
       # MacPorts
       SET(INSTALL_OSX_BUNDLE_DIR /Applications/MacPorts CACHE DOCSTRING
 "Install directory Hugin and HuginStitchProject application bundles")
     ELSE(CMAKE_INSTALL_PREFIX STREQUAL "/opt/local")
       # fink or other custom system.
       SET(INSTALL_OSX_BUNDLE_DIR ${CMAKE_INSTALL_PREFIX}/Applications
 CACHE DOCSTRING "Install directory Hugin and HuginStitchProject
 application bundles")
     ENDIF(CMAKE_INSTALL_PREFIX STREQUAL "/opt/local")

 This means that it looks to /opt/local by default on Apple, but if another
 CMAKE_INSTALL_PREFIX is specified it will take that one. I use it myself
 as well to define other locations for test builds (especially at
 /usr/local). I thought that macports set it's own CMAKE_INSTALL_PREFIX as
 part of the "PortGroup cmake 1.0" option. No matter whether macports is
 really in /opt or in some other location, the macports
 CMAKE_INSTALL_PREFIX will be picked up by the CMake file. Or doesn't
 macports set this cmake variable?

 Other files that possibly seem to hardcode /opt and /sw are the cmake
 macros FIND<whatever>. In these files also /usr, /usr/local, etcetera are
 hardcoded to make cmake find libraries/frameworks at places other than the
 system paths.
 If this hardcoded paths are also in other parts, please let me know.
