CMake ошибка в CLion

Всем привет.

В CLion при попытке использовать Cygwin возникает ошибка такого рода:

C:\Users\DavidOS\.CLion2016.3\system\cygwin_cmake\bin\cmake.exe -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - Unix Makefiles" /cygdrive/c/Users/DavidOS/CLionProjects/FooBar

  The C compiler "/usr/bin/cc" is not able to compile a simple test program.
  It fails with the following output:

Хотя всё вроде как установлено правильно и никаких ошибок в toolchain нет

В Path Cygwin тоже есть: C:\cygwin64\bin В чём может быть ошибка?
