redefined data types in different packages - request for help

[Michael Dickens]

Using "-isystem ${prefix}/include" seems like a great solution to using
CPATH; it seems to work all the way back to clang 2.9 and gcc 4.2,
maybe further, while CPATH started with (I think) clang 2.9 -- I'll
have to investigate using it for qt4-mac.



I use LIBRARY_PATH instead of setting LDFLAGS, which works with gcc 4.2
or newer, probably much older too, but only clang 3.0 or newer (again,
I think).  I find no good flags such as -isystem to do libraries in
this way. - MLD

Hi Mojca - Since the CMake PortGroup was recently modified to include

CPPFLAGS="-I${prefix}/include", I've been having to remove that setting

from my ports which use this group because it grabs already-installed

headers instead of those local to the port (CPPFLAGS gets propagated to

CFLAGS and CXXFLAGS).



[1]https://trac.macports.org/ticket/40656 should fix this.



Ditto for LDFLAGS and "-L${prefix}/lib".



But not this. I'm not aware of a similar directive we could use to fix
this for libraries.
