Hi, Qt find glib2 using this code https://github.com/qt/qtbase/blob/dev/cmake/3rdparty/extra-cmake-modules/find-modules/FindGLIB2.cmake which uses pkg-config underneath.
According to https://askubuntu.com/questions/210210/pkg-config-path-environment-variable you can try setting the PKG_CONFIG_PATH env variable to the location of your newly installed glib. According to https://cmake.org/cmake/help/latest/module/FindPkgConfig.html#variable:PKG_CONFIG_USE_CMAKE_PREFIX_PATH it should be also possible to add a path to the CMAKE_PREFIX_PATH cache var, which will be treated as an extra pkg-config prefix. You would pass it to configure like ./qtbase/configure -debug -- -DCMAKE_PREFIX_PATH=/some/path So i would play around with those alternatives. > On 9.
