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?
