[srslte-users] Compilation problem - resolved

[Paul Sutton]

Just an update on this for anyone else on the list with the same problem.
The problem was caused by an incomplete detection of Matlab by CMake.
Matlab is notoriously difficult to correctly detect and build against
with CMake due to changing library names and include paths between
different versions.
Matlab is only used by srsLTE to optionally build MEX files. It is not
required to build and use the library so we've disabled this feature by
default.
When pulling from the repo and rebuilding, make sure to clean out your
build directory so cached CMake variables (CMakeCache.txt) aren't used.

Regards,
Paul
