To give more details about this for people who are interested.
At OVS side, we tried to link the DPDK library, by doing below at
meson.build file
libdpdk = dependency('libdpdk', method: 'pkg-config')" , or give
it a specific path
libdpdk = cc.find_library('dpdk', dirs: ['C:\\temp\\dpdk\\lib'])
However, it doesn't work, with error below
Run-time dependency libdpdk found: NO (tried pkgconfig)
meson.build:45:4: ERROR: Dependency "libdpdk" not found, tried pkgconfig
On the other hand, pkg-config seems OK for locating the dpdk library.
PS C:\k8s-antrea-dpdk-win\ovs> pkg-config --list-all
libdpdk DPDK - The Data Plane Development Kit (DPDK).
libdpdk-libs dpdk-libs - Internal-only DPDK pkgconfig file. Not for direct use.
We are using meson 0.59.0 and pkg-config-lite 0.28
Currently we can work around it by linking the rte_xxx.lib one-by-one.
rte_eal_lib = cc.find_library('rte_eal', dirs: ['C:\\temp\\dpdk\\lib'])
rte_ethdev_lib = cc.find_library('rte_ethdev', dirs:
['C:\\temp\\dpdk\\lib'])

William
