I'm wondering if anyone can help me figure out why this is happening? it 
looks like it was when meson was upgraded to 0.60.0.

I'm building on Arch Linux, with rdma-core 37.0 already installed 
(custom built).

Here is my build commands for rdma-core (no problem)...

        mkdir -p build
        cd build
        cmake \
                -GNinja \
                -DENABLE_VALGRIND=0 \
                -DCMAKE_BUILD_TYPE='Release' \
                -DCMAKE_INSTALL_PREFIX='/usr' \
                -DCMAKE_INSTALL_RUNDIR='/run' \
                -DCMAKE_INSTALL_SBINDIR='/usr/bin' \
                -DCMAKE_INSTALL_LIBDIR='/usr/lib' \
                -DCMAKE_INSTALL_LIBEXECDIR='/usr/lib/rdma' \
                -DCMAKE_INSTALL_SYSCONFDIR='/etc' \
                -DCMAKE_INSTALL_PERLDIR='/usr/share/perl5/vendor_perl' \
                ..
        ninja


Here is my build command for dpdk...

meson -Dplatform=generic -Dexamples=all build --prefix=/usr
        ninja -C build

gcc 11.1.0

meson 0.60.0
