Alexander,
The current code path used during the execution of 'fink dumpinfo -eLDFLAGS'
and 'fink dumpinfo -eCPPFLAGS' won't be able to detect this auto-append as
the test for the presence of the BuildDepends on x11-dev must be done in
resolve_depends() when the dependencies are being collated.
My tests have been done brute force by adding...
echo $CPPFLAGS;
echo $LDFLAGS;
at the front of the CompileScript in xft2-dev. which on darwin14 produces...
echo $CPPFLAGS;
-I/sw/include -I/opt/X11/lib
echo $LDFLAGS;
-L/sw/lib -L/opt/X11/lib
in the build log while...
% fink dumpinfo -eCPPFLAGS xft2-dev
Scanning package description files..........
Information about 10430 packages read in 2 seconds.
CPPFLAGS=-I/sw/include
% fink dumpinfo -eLDFLAGS xft2-dev
Scanning package description files..........
Information about 10430 packages read in 1 seconds.
LDFLAGS=-L/sw/lib
