This find_program() is executing inside the try_compile (separtely
from the instance in the main project).  That's the one that fails
to find it even though it is set in the outer project.

My guess is that _CMAKE_TOOLCHAIN_LOCATION is not making it into
the try_compile-d project CMake code.  You'll have to add it to
the try_compile call with the CMAKE_FLAGS option.
