| |/ | | | | | | | | | | | | | | | | | | | | If a distro-specific "trellis-devel" package is used, the pytrellis.so library might be located in a dedicated directory, rather than under TRELLIS_ROOT. Search for pytrellis.so in a list of directories, then subsequently use the first match as part of PYTHONPATH. Signed-off-by: Gabriel Somlo <gsomlo@gmail.com>
