Cmake c compiler not set

[Sam1370]

I have this error although I have the xcode command lines tool installed:

CMake Deprecation Warning at CMakeLists.txt:15 (cmake_policy):
  The OLD behavior for policy CMP0046 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.

Seem like it cannot find macOS sdk directory. Could you please make sure it's there /Library/Developer/CommandLineTools/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk?

And what is the result from executing this xcode-select -p on your terminal?

Solved, I changed the variables at the beginning to match my system

POSTFIXPATH_SDKROOT=/SDKs/MacOSX10.14.sdk
CCPATH_TOOLCHAIN=/usr/bin/cc
CXXPATH_TOOLCHAIN=/usr/bin/c++
