David Sterba ab5984ff6c btrfs-progs: convert: drop dependency on sys/acl.h
The file sys/acl.h is part of libacl and if the development package is
not installed, build of btrfs-convert fails.

We do not link against libacl nor use the functions provided by libacl.  The
ACL_* values are directly read from the extN data, so it's more part of the
on-disk format rather than an interface to libacl.

The dependency on libacl is completely dropped.

=========================
The Btrfs utility programs require the following libraries/tools to build:
- libuuid - provided by util-linux, e2fsprogs/e2fslibs or libuuid
- libblkid - block device id library
- liblzo2 - LZO data compression library
- zlib - ZLIB data compression library
For the btrfs-convert utility:
- e2fsprogs - ext2/ext3/ext4 file system libraries, or called e2fslibs
Generating documentation:
- asciidoc - text document format tool
- xmlto - text document format tool
XATTR library should be provided by the standard C library or by
- libattr - extended attribute library
Please note that the package names may differ according to the distribution.
See https://btrfs.wiki.kernel.org/index.php/Btrfs_source_repositories#Dependencies .
To build from git sources you need to generate the confiture script using the
autools:
$ ./autogen.sh
To build from the released tarballs:
$ ./configure
$ make
$ make install
You may disable building some parts like documentation, btrfs-convert or
backtrace support. See ./configure --help for more.
Specific CFLAGS or LDFLAGS should be set like
$ CFLAGS=... LDFLAGS=... ./configure --prefix=/usr
and not as arguments to make.
