Adding an external static library to OOT module

[Eugene Grayver]

Hello,

I want to add an external library (say /home/user/libmy.a) to an OOT module.  
Note that this library is not  in the same folder structure as the oot-module. 
I can easily add it to the library in lib/CmakeFiles.txt.  However, it also 
needs to be added (AFAIK) to the CmakeFiles.txt in 
python/bindings/CmakeFiles.txt.  In the 'olden days' of 3.7, the SWIG-based 
built allowed me to add this.  However, the new GR_PYBIND_MAKE_OOT macro does 
not seem to allow it.

Any suggestions?

Thanks.
