|
The commit changed the detection path due to FreeBSD issues,
|
|
but apparently affects also Openwrt buildroot negatively.

Original explanation:

Subject: [PATCH] Fix libmodbus detection on FreeBSD
|
|
|
|
We look for modbus/modbus.h in /usr/local/include/modbus
|
|
but we should look for modbus.h
|
|
|
|
This is only an issue on FreeBSD since /usr/local/include is not
|
|
in the default search path.
