I just had a look at gr-osmosdr-0.1.4.127-3.mga7.src.rpm and this is not using the official code from the gr3.8 branch of git.osmocom.org/gr-osmosdr The code in that repo at absolutely no point will ever look for a pkg config file. In 3.8 the modules install 3 cmake specific files : gnuradio-osmosdrConfig.cmake gnuradio-osmosdrTargets.cmake gnuradio-osmosdrTargets-release.cmake and these contain all the informations needed by cmake to know which libraries to link and which include directory the add to the include path and any dependency on other cmake modules. Theses are also automatically generated by cmake, without the need to duplicate the information in another file. If you look at CMakeList for iqbal for instance : target_include_directories(gnuradio-iqbalance PRIVATE ${LIBOSMODSP_SEL_INCLUDE_DIRS} PUBLIC ${Boost_INCLUDE_DIRS} PUBLIC $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/../include> PUBLIC $<INSTALL_INTERFACE:include> ) the PRIVATE / PUBLIC / INTERFACE / ... are all specifiers for cmake to generate those files properly and include everything needed automatically. If this doesn't work for you, either : - You're not using the right source as pointed out above ... - Something is broken in the gr-iqbal / gr-osmosdr CMake that makes it not work properly ( wronge PRIVATE / PUBLIC specifier or something omitted or something like this ) - Something else in your setup is broken that breaks cmake's module system In anycase, none of this requires pkg-config files.
