The build system for libvirt correctly detects the location of blkid using PKG_CONFIG_PATH environment variable. The file blkid.pc states that the include flags should be: 'Cflags: -I${includedir}/blkid' but libvirt searches for blkid.h inside ${includedir}/blkid/blkid, which is wrong. Until now, the compilation for libvirt succeeded because of pure luck, as it had -I/usr/include as a CFLAG. This issue was faced while compiling libvirt on Ubuntu 16.04.2 with bare minimum dev packages and a custom compiled blkid kept in a non-standard $prefix.
