Global default settings for cmake

Question

Is there anything similar to MAKEFLAGS environment variable for cmake, to set some global defaults like CMAKE_INSTALL_PREFIX?

Answer 1

No, there is no similar environment variable for CMake. Everything you can set through environment variables in CMake is documented here.

But you could use a the "preload cache" -C option and put all reoccurring settings in an appropriate script (see e.g. CMake preload script for cache).
