Hi Chris,
Thanks for your answer, I am not sure of what I should do to some of your tips. So, let's start with this one :

- Compile only the necessary drivers.

INDI library has many drivers that we do not need as we are using only our cutom 'Mount' driver. So how could I do this ? By removing lines in some of the CMakeList.txt ?
I have no experience in the cmake system ...

Another one that could be easy : Do all the compiling on the SD card.

I think that I could mount a blank SD card in the file system (for example in Project directory) so the INDI library could be in the SD card. But in that case will the install process still be in the same directory.

Sory for these very basic questions, but I am no guru in INDI nor in Beaglebone ...
