Comment:

 The problem is, cmake always has `-I/opt/local/include` hardcoded and adds
 other paths specified with `include_directories(...)` at the end. Of
 course, this ends up in the wrong order, with `-I/opt/local/include` at
 the front while it should be the last.

 I tried to fix this in r71635 by adding this flag to cmake, as
 [http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:include_directories
 described in their documentation]:

 `-DCMAKE_INCLUDE_DIRECTORIES_BEFORE=ON`

 For me on Snow Leopard 10.6.4 using cmake @2.8.2_2+gui. ffmpeg @0.6_2 was
 active and installed at the same time, the build still was ''okay''. But
 this could still mean it is picking up wrong headers :-)

 And actually, you are right the order is still wrong even for me while
 building plugins:
 {{{
 ...
 -I/opt/local/include
 -I/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_multimedia_avidemux/work/avidemux_2.5.3/avidemux/ADM_libraries/ffmpeg
 ...
 }}}

 I am adding css@ as cmake maintainer to CC as he might have a hint where
 to look at for this problem. I am clueless at the moment...
