Why CMake can't run as make ?

CMake parse CMakeLists.txt, generate Makefile.  Then, make parse the
Makefile,  and execute(serially or parallelly) shells,  shells run
comands(compiler, etc) to build.

Perhaps, CMake can parse CMakeLists.txt, and directly run
comands(compiler, etc) to build,  without gererating Makefile,
invoking make, invoking shells.
