#57990: libxml2 @2.9.7_2: ICU include directory not in pkg-config output
----------------------+---------------------
 Reporter:  dsedivec  |      Owner:  (none)
     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.5.4
 Keywords:            |       Port:  libxml2
----------------------+---------------------
 Since [https://github.com/macports/macports-ports/commit/0ed53fa9e884ed50
 libxml2 now builds against ICU], I cannot build software against MacPorts
 libxml2 without manually including `-I$prefix/include` when building.
 Quick example:

 {{{
 $ command -v pkg-config
 /opt/local/bin/pkg-config

 $ cat repro.c
 /* Include inspired by PostGIS's configure script: */
 #include <libxml/tree.h>

 int main() { return 0; }

 $ clang $(pkg-config --cflags libxml-2.0) repro.c $(pkg-config --libs
 libxml-2.0)

 #include <unicode/ucnv.h>
          ^~~~~~~~~~~~~~~~

 $ clang -I/opt/local/include $(pkg-config --cflags libxml-2.0) repro.c
 $(pkg-config --libs libxml-2.0)

 $ ls a.out
 a.out*
 }}}

 After a brief conversation on IRC it was requested that I open a ticket
 for this, since the ICU cflags/libs flags should probably be included in
 pkg-config output for libxml-2.0 now.  (It was also suggested that maybe
 this is really an upstream issue, rather than MacPorts.)
