Isn't wiringpi mainly a library ? Maybe it should go under Libraries ->
Hardware handling.

This patch is not correct I believe. It makes the assumption that
wiringPi is already installed in $(DESTDIR)$(PREFIX), which it is not
when you are building it.

It would be a lot better to use $(TARGET_CONFIGURE_OPTS), and
$(TARGET_MAKE_ENV), i.e:
$(TARGET_MAKE_ENV) $(TARGET_CONFIGURE_OPTS) $(MAKE) -C $(@D)/wiringPi
the CC=$(TARGET_CC) is already part of TARGET_CONFIGURE_OPTS. Also you
will probably have to adjust the Makefile to turn CFLAGS = into CFLAGS
+=.

Why are you doing installation within the <pkg>_BUILDS_CMDS ? This is not good ?

Why is DESTDIR= needed here ?

Ditto installation.

This is not good because $(INSTALL) -D expect a full destination path.
I guess the easiest is just:
cp -dpfr $(@D)/wiringPi/*.h $(STAGING_DIR)/usr/include

Same comments here: $(INSTALL) -D requires a full destination path.
Otherwise, if $(TARGET_DIR)/usr/bin doesn't exist as a directory, you
will have you "pintest" program installed as "bin" in $(TARGET_DIR)/usr.
Moreover, the upstream project has some "install" and "install-static"
targets. You should use them instead of doing manual installation.
Finally, if you're installing unconditionally shared libraries, then it
means that they are always being built. So your package should depend
on !BR2_STATIC_LIBS.
Can you fix those comments and send an updated version ?
Thanks!
Thomas

Intention was to set DESTDIR/PREFIX values to the build directory to avoid
the install step before linking gpio (as the original build script does)...

Did not work, because the original Makefile used 'CC=gcc' which is only
overridden by command line options, not by environment variables...

Because I tried to not patch the original build system which assumes:
- build wiringPi, install wiringPi
- build devLib, install devLib
- build gpio, install gpio
But will complete rework my patch...
