Description of problem:
Many of the wireshark header files depend on glib, since they #include glib.h.

$ rpm -q wireshark-devel
wireshark-devel-1.12.9-1.fc23.x86_64

$ rpm -ql wireshark-devel | grep include | grep '\.h' | xargs grep glib.h | wc -l
122


Historically wireshark.pc has included 'Requires: glib-2.0' so that pkg-config can report the correct cflags to build wireshark packet dissectors

$ pkg-config --cflags --libs wireshark
-DWS_VAR_IMPORT=extern -DHAVE_STDARG_H -DWS_MSVC_NORETURN= -pthread -I/usr/include/wireshark -I/usr/include/wireshark/epan -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -lwireshark -lwiretap -Wl,--export-dynamic -lgmodule-2.0 -pthread -lglib-2.0 



So on Fedora 23 with wireshark-1.12.9 you can do

$ cat > ws.c <<EOF

#include <wireshark/config.h>
#include <wireshark/epan/proto.h>
EOF
$ gcc -c `pkg-config --cflags --libs wireshark` -o ws.o ws.c

And it works.


In Fedora 24, with wireshark-2.0.1, the wireshark.pc file has been changed so that it only has 'Requires: Qt':

$ rpm -q wireshark-devel
wireshark-devel-2.0.1-1.fc24.x86_64

$ pkg-config --cflags --libs wireshark
-DWS_VAR_IMPORT=extern -DHAVE_STDARG_H -DWS_MSVC_NORETURN= -I/usr/include/wireshark -I/usr/include/wireshark/epan -lwireshark -lwiretap 


but even more of the header files still #include <glib.h>:


$ rpm -ql wireshark-devel | grep include | grep '\.h' | xargs grep glib.h | wc -l
128


As a result, when trying to compile dissectors, the compiler is no longer able to locate the glib header files

$ gcc -c `pkg-config --cflags --libs wireshark` -o ws.o ws.c 
In file included from ws.c:3:0:
/usr/include/wireshark/epan/proto.h:40:18: fatal error: glib.h: No such file or directory
compilation terminated.



This flaw is making it impossible to build libvirt's wireshark support as it canot find glib.


Version-Release number of selected component (if applicable):
wireshark-devel-2.0.1-1.fc24.x86_64

How reproducible:
Always

Steps to Reproduce:
1. See example program above
2.
3.

Actual results:
Compiler cannot find glib.h due to missing cflags from pkg-config wireshark.pc

Expected results:
wireshark.pc includes all flags neccessary to compile against wireshark.
