use QJDns cmake config module

[drizt]

jdns/qjdns provides cmake config module. So they should be used instead of pkg-config in CMake. Replace

    # For Linux it was found already before at line 29
    if(NOT LINUX)
            find_package(PkgConfig)
    endif()
    pkg_search_module(JDNS REQUIRED qjdns)

with

find_package(QJDns)

Note. The latest jdns-2.0.3 provides coinstallable Qt4/Qt5 versions of qjdns. So find_package(QJDns)
is good for both

Hi,
Jreen doesn't use jdns library in case of Qt5 as latter has built-in QDnsLookup class. Also what is a benefit of searching jdns by find_package instead of pkg_search_module?

[drizt]

qjdns.pc was renamed to qjdns-qt4.pc in jdns-2.0.3. CMake config file name was not changed. Also cmake config module provides qjdns target which more suitable. With qjdns target no need to explicity set jdns include dir. It enough to do target_link_libraries(${PROJECT_NAME} qjdns). Also cmake is not recommended to use pkg-config when there is cmake module.

Makes sense, thank you for information. I'll try to update it today.
