During compilation of customized distribution (using buildroot v. 11.2018) I have problem with libmount library (the problem appeared after I had included efl package in buildroot menuconfig - *Target packages -> Graphic lib... -> efl* ). I have additionaly installed package libmount-dev with no results. checking for getxattr in -lc... yes checking sys/xattr.h usability... yes checking sys/xattr.h presence... yes checking for sys/xattr.h... yes checking for XATTR_NOFOLLOW... no checking for LIBMOUNT... no configure: error: *** Could not find libmount How to include this library to obtain succesful compilation?
