if you use "devtool build" from the extensible SDK to build a recipe
that inherits cmake.bbclass, then the function cmake_do_configure() will
be called implicitly.

But if you manually compile a cmake project with the SDK, then that
function won't be used. If your SDK contains the package
nativesdk-cmake, then the SDK contains the following file:

  $OECORE_NATIVE_SYSROOT/environment-setup.d/cmake.sh

This file will be sourced along with the rest of the SDK and set an
alias for cmake with an SDK-specific toolchain file.

To verify if the option CMAKE_NO_SYSTEM_FROM_IMPORTED has been set by
cmake, you can check if the file CMakeCache.txt (in the build directory)
contains an entry for CMAKE_NO_SYSTEM_FROM_IMPORTED. An alternative way
is to inspect the configuration via ccmake after calling cmake.

Best regards,
Dennis
