[Dune] CMake - GMP

[Christian Kaltenecker]

Hello Dune,

I am currently trying to include the GMP library. Therefore, I have
created an opt-file and included it to dunecontrol.
Although I have set the GMP_ROOT-variable properly, the FindGMP-script
has started searching for the header in /usr/ and finds my system GMP
library instead of my self-compiled GMP library.
How can I make it use the self-compiled library?

Thanks in advance!

Best regards,
