My current system is using xenomai real-time kernel, kernel version 4.9.38. Use ldd lcec.so

linux-vdso.so.1 => (0x00007ffed138e000)

libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc43f3ac000)

/lib64/ld-linux-x86-64.so.2 (0x00007fc43f989000)

There is no error, but the link to the ecat library is not available. How to solve it?

I think #122 is supposed to fix this, but it doesn't produce a change in my build. Looking into it a bit more.
