### Set up build environment ##################################################
# Choose a static or shared-library build (shared is default, and static will
# probably need some special care!)
# Set this to ON in order to link a static build of UHD:
option(UHD_USE_STATIC_LIBS OFF)
find_package(PkgConfig)

# To add UHD as a dependency to this project, add a line such as this:
find_package(UHD)
find_package(Boost COMPONENTS thread system program_options REQUIRED)
find_package(Curses REQUIRED)

# The version in  ^^^^^  here is a minimum version.
# To specify an exact version:
#find_package(UHD 3.15.0 EXACT REQUIRED)

# This example also requires Boost.
# Set components here, then include UHDBoost to do the actual finding
