The Makefile for each CMakeLists.txt file is always generated in the 
build tree with the same relative path as in the source tree:

myproj-source/CMakeLists.txt -> myproj-build/Makefile
myproj-source/Foo/CMakeLists.txt -> myproj-build/Foo/Makefile

The build tree is specified in the CMakeSetup dialog in Windows or as 
the current working directory from the UNIX or Windows command line:

$ ls -d myproj-source
myproj-source/
$ mkdir myproj-build
$ cd myproj-build
$ cmake ../myproj-source

The book "Mastering CMake" has a section listing them:
