[dpdk-dev] [PATCH v4 2/2] build: add drivers_install_subdir meson option

Luca Boccassi bluca at debian.org
Tue Oct 2 18:20:46 CEST 2018

Allow users and packagers to override the default dpdk/drivers
subdirectory where the PMDs get installed under $lib.

Signed-off-by: Luca Boccassi <bluca at debian.org>
v3: changed default value to <VERSION> and use string.contains rather
    than exact equivalence
v4: further optimisations suggested by review
