cmake: set variables set by project call

Browse source 
ESP-IDF overrides project() definition for user convenience. This
redefinition lacks setting the variables documented at
the project command documentation
https://cmake.org/cmake/help/v3.5/command/project.html in the parent
scope.

This commit sets those variables.

Closes https://github.com/espressif/esp-idf/issues/3611.
