Cmake error

[AakashKT]

I am trying to build layerlab, cmake gives the following warning :

CMake Deprecation Warning at ext/tbb/CMakeLists.txt:11 (cmake_policy):
  The OLD behavior for policy CMP0023 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

ccmake does not let me proceed with this warning.

However, after cmake, when i do make -j4, it gives many more errors, which I think are to do with the c++ version.
One such error:

static const float  OneMinusEpsilon_f = 0x1.fffffep-1f;

Any tips on how I can build layerlab? Is this a version issue?
Thanks!

PS: My use case is to convert .binary files from MERL to .bsdf to use in PBRT. Do let me know if another tool for this exists :-)
