Query Fedora build dependencies:
# Which packages have SDT tracepoints enabled?
fedora-source-query --whatrequires systemtap-sdt-devel

# NOTE: Since "sys/sdt.h" is a header only library,
# you can't get this information by querying the provies / requires in arch specific repositories

# Which packages depends on gtk3-devel to build?
fedora-source-query --whatrequires gtk3-devel

# which build dependencies does gtk3 itself have?
# Use an SRPM name here, ex: gtk3 instead of gtk3-devel
fedora-source-query --requires gtk3
