CMake files have the suffix ".cmake".
Emacs does not appear to handle them, you end up in Fundamental mode.

GNU Emacs 24.5.1 (x86_64-redhat-linux-gnu, GTK+ Version 3.14.12) of 2015-05-07 
on buildvm-08.phx2.fedoraproject.org

They look like a script with '#' comments so there might be a mode that
would come close:

  # Install script for directory: /home/me/src/libomron

  # Set the install prefix
  IF(NOT DEFINED CMAKE_INSTALL_PREFIX)
    SET(CMAKE_INSTALL_PREFIX "/usr/local")
  ENDIF(NOT DEFINED CMAKE_INSTALL_PREFIX)
  STRING(REGEX REPLACE "/$" "" CMAKE_INSTALL_PREFIX "${CMAKE_INSTALL_PREFIX}")

So, tab should just self insert.

For the original poster:

In Emacs, the tab key works differently depending on the mode.
The mode is often set automatically based on the file extension.
You can see the mode inside () on the mode line, its the first word.

If you are in fundamental mode, the tab key should insert a tab.
Emacs by default tabs by 8.

All of this can be changed, but don't do it to fundamental mode.
