I did something similar to find gsoap. It should give you some ideas:

GSOAP_PC = gsoapssl++
!packagesExist($$GSOAP_PC):GSOAP_PC = gsoap++
!packagesExist($$GSOAP_PC):error("Package gsoap not not found")

# Use pkg-config for gsoap the hard way.
isEmpty(PKG_CONFIG):PKG_CONFIG = pkg-config
QMAKE_CXXFLAGS += $$system($$PKG_CONFIG --cflags $$GSOAP_PC)
QMAKE_CFLAGS += $$system($$PKG_CONFIG --cflags $$GSOAP_PC)
# GSOAP_PREFIX needed to find configuration files
GSOAP_PREFIX = $$system($$PKG_CONFIG --variable=prefix $$GSOAP_PC)
message(Using $$GSOAP_PC from $$GSOAP_PREFIX)
