 Can't really include the mpv library at any .c file (even adding the
 +libmpv variant)! Here's a real exemple:

 {{{#!shell
 $ sudo make install
 cc -std=c99 -Wall -Wextra -pedantic -Wunused-result -Wno-unused-variable
 -Os -D_POSIX_C_SOURCE -DTOMATONOISE=\"/usr/local/bin/tomatonoise\"
 -DLOGPREFIX=\".local/share/tomato\"
 -DLOGFILE=\".local/share/tomato/tomato.log\"
 -DTMPFILE=\".local/share/tomato/tmp.log\"
 -DTIMERFILE=\".local/share/tomato/time.log\"
 -DNOTEPADFILE=\".local/share/tomato/notepad.log\" -I/usr/local/include
 -L/usr/local/lib  tomatonoise.c  `pkg-config --libs ncursesw mpv` -o
 tomatonoise
 tomatonoise.c:1:10: fatal error: 'mpv/client.h' file not found
 #include <mpv/client.h>
          ^~~~~~~~~~~~~~
 1 error generated.
 make: *** [tomatonoise] Error 1
 Error: Process completed with exit code 2.
