GTest - isatty not declared in this scope - c++

Question

I've spent hours trying to figure out why I'm getting the following compiling error:
~/src/example/build $ make

I'm using the FindGMock.cmake from the cucumber-cpp project to handle the GTest dependency.
In my CMakeLists.txt file I have:
add_executable(step_definition_runner
features/step_definitions/App_Steps.cpp
)
target_include_directories(step_definition_runner
PRIVATE
${GTEST_INCLUDE_DIRS}
)
target_link_libraries(step_definition_runner project-app ${GTEST_LIBRARIES})
I've tried many things, but a couple of note:
Including unistd.h before I include gtest/gtest.h.
Force including unistd.h inside gtest/gtest.h and gtest/internal/gtest-port.h.
Is there something obvious I'm missing?

It seems like you are not on windows OS.
These functions are allowed only for windows
Look for below content in
https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h
402 // Brings in definitions for functions used in the testing::internal::posix
403 // namespace (read, write, close, chdir, isatty, stat). We do not currently
404 // use them on Windows Mobile.
405 #if GTEST_OS_WINDOWS
406 # if !GTEST_OS_WINDOWS_MOBILE
407 # include <direct.h>
408 # include <io.h>
409 # endif
