media-libs/libsfml has pkg-config files upstream, but they aren't installed by default. It is necessary to pass "-DSFML_INSTALL_PKGCONFIG_FILES=true" to cmake in order to get them to install. Reproducible: Always Steps to Reproduce: 1. install media-libs/libsfml-2.2 2. pkg-config sfml-all --libs Actual Results: pkg-config doesn't find a sfml-all pkg-config file Expected Results: pkg-config does find a sfml-all pkg-config file I'll attach a patch that unconditionally installs the pkg-config files.
Created attachment 402408 [details, diff] Enables pkg-config file installation I'm not sure if this is the right format for mycmakeargs, but this does end up installing the pkg-config files for me.
in portage. thanks for the bug report and patch.
