gps-sdr-simのhackplayerをmakeでコンパイルする

Windows 11 ProのWLS 2上のUbuntu 24.04.3でgps-sdr-simのplayerにあるhackplayer.cをmakeでコンパイルしたところエラーになりました。

$ make hackplayer
make: pkg-config: No such file or directory
make: pkg-config: No such file or directory
make: pkg-config: No such file or directory
cc -std=c11 -O3 -g -W -Wall      -c -o hackplayer.o hackplayer.c
hackplayer.c:22:10: fatal error: libhackrf/hackrf.h: No such file or directory
   22 | #include <libhackrf/hackrf.h>
      |          ^~~~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [<builtin>: hackplayer.o] Error 1

pkg-configがないとのことで、インストールします。

$ which pkg-config
$sudo apt-get install pkg-config
$ which pkg-config
/usr/bin/pkg-config

続いてlibhackrfがないとのこと。

$ make hackplayer
Package libhackrf was not found in the pkg-config search path.
Perhaps you should add the directory containing `libhackrf.pc'
to the PKG_CONFIG_PATH environment variable

libhackrfはhackrfに入ってるのですが、libhackrf-devなるものをインストールすればいい、みたいな記事を見かけたので入れてみました。
