Installation Requirements
OpenBTS compiles to a simple Unix binary and does not require special
installation.
One some systems (Ubuntu), you will need to define LIBS = -lpthread prior to
running configure.
To run OpenBTS, the following should be installed:
Asterisk (http://www.asterisk.org), running SIP on port 5060.
libosip2 (http://www.gnu.org/software/osip/)
libortp (http://freshmeat.net/projects/ortp/)
libusrp (http://gnuradio.org).
This is part of the GNURadio installation.
It is the only part used by OpenBTS.
OpenBTS logs to syslogd as facility LOG_LOCAL7. Please set your /etc/syslog.conf
accordingly.
For information on specific executables, see tests/README.tests and
apps/README.apps.
See http://gnuradio.org/redmine/wiki/gnuradio/OpenBTS/BuildingAndRunning for more
information.
This is special branch for XTRX support. It should be configured with cmake, autoconf isn't supported yet.

# - Find the XTRX library
#
# Usage:
# find_package(XTRX [REQUIRED] [QUIET] )
#
# It sets the following variables:
# XTRX_FOUND ... true if XTRX is found on the system
# XTRX_LIBRARIES ... full path to XTRX library
# XTRX_INCLUDES ... XTRX include directory
#
# The following variables will be checked by the function
# XTRX_USE_STATIC_LIBS ... if true, only static libraries are found
# XTRX_ROOT ... if set, the libraries are exclusively searched
# under this path
# XTRX_LIBRARY ... XTRX library to use
# XTRX_INCLUDE_DIR ... XTRX include directory
#
#If environment variable XTRXDIR is specified, it has same effect as XTRX_ROOT
if( NOT XTRX_ROOT AND ENV{XTRXDIR} )
