CMake Error: The inter-target dependency graph contains the following strongly connected component (cycle):

  "nel_drv_opengl" of type STATIC_LIBRARY

At least one of these targets is not a STATIC_LIBRARY.  Cyclic dependencies are allowed only among static libraries.

-DWITH_STATIC_DRIVERS=OFF seems to fix the error, but I think it may be needed. Am I doing something wrong?

[nimetu]

You need to add -DWITH_STATIC=ON -DWITH_STATIC_DRIVERS=ON By default it compiled libnel.so shared library and then drivers needs to be shared libraries aswell.

[Langerz82]

@nimetu builds find with -DWITH_STATIC=ON added, thanks allot and closing issue, cheers.
