Setting Xcode Environment Variable from CMake

Question

I'm working in an Xcode project created using CMake. I would like to be able to automatically create an environment variable in Xcode using CMake commands, but it doesn't appear to work.

In my .profile I have

export WORKDIR=$HOME/temp/working

and I would like to have it appear in Xcode as an environment variable such as the follow picture (or equivalent)

so that I can load it in C++ using the following:

auto workdir  = std::getenv("WORKDIR");

I tried using the following command:

set($ENV{WORKDIR} ${WORKDIR})

but it didn't seem to help. Any ideas?

Set it as the following in an initial cache file

set(CMAKE_XCODE_SCHEME_ENVIRONMENT
  ASAN_OPTIONS=$ENV{ASAN_OPTIONS}
  LSAN_OPTIONS=$ENV{LSAN_OPTIONS} CACHE STRING "" FORCE)

to be used as cmake -C thefile.cmake -G Xcode ..

or

-DCMAKE_XCODE_SCHEME_ENVIRONMENT="ASAN_OPTIONS=${ASAN_OPTIONS};LSAN_OPTIONS=${LSAN_OPTIONS}"

to be used by passing it to cmake directly.
