Subject: [PATCH] Adjust for buildroot build.
|
|
|
|
- enable CC override
|
|
- fix devLib/gpio include path for local build (without installing first)
|
|
- change CFLAGS from '=' to '+=' to honour buildroot given flags
|
|
- add linker name link for libwiringPiDev and libwiringPi for local linking
|
|
(without installing first)
|
|
- fix install linker name link (do not link with absolute path)
|
|
- add gpio-static linking target
|
