Adding library to new C++ hardware plugin Topic is solved

[rafal9318]

Hi All,

I have a question about adding the library to CMakeLists.txt file, to corretly compile and link new hardware with Domoticz source.
I'm creating new hardware in C++, new hardware in based on Dummy hardware. I copied it and change names.
But now i need to add to this new hardware library #include <modbus/modbus.h>
This library: https://github.com/stephane/libmodbus

I put src files in ../hardware/modbus directory.

And now i need to know how to add this library to CMakeLists.txt file, to correctly compile and link library, and to use functions (for example modbus_read_bits(...) ) from modbus library in new hardware (for example in Do_Work() method).

I tried, just to add this line to CMakeLists/txt:
hardware/modbus/modbus.c

but after make i've got"

[ 12%] Building CXX object CMakeFiles/domoticz.dir/cmake_pch.hxx.gch

make: *** [Makefile:172: all] Error 2

Please help.

Is the solution worth to share?
Maybe other forum members don't have to search for it when they have the same question / issue.
