I found an interesting discussion on Stack Overflow: http://stackoverflow.com/questions/10220946/pkg-check-modules-considered-harmful
One key point is in this part of the 1st answer: "If a user installs libfoo in /p/a/t/h and invokes a configure script with LDFLAGS=-L/p/a/t/h, the user is justified in expecting the configure to find libfoo. But, the user also must set PKG_CONFIG_PATH so that the configure script can find foo.pc in order for the configury to succeed, and IMO that is broken." We're one of the people who deal with these settings a lot, I wonder if we can contribute something to this conversation. Maciej
