Exporting cmake-gui options

I have a library with a bunch of different configuration options. We usually configure the build with cmake-gui and ticking a few checkboxes.

I want to automate this into a .sh script using just cmake.

e.g.
In GUI -> selects a bunch of different options
equivalent cmake command -> cmake -D CMAKE_XXX=X -D CMAKE_XXY=XXY [a bunch of options here] ..

How can I find the "equivalent" cmake command-line command to any arbitrary configuration I choose from the GUI?

You can write a file containing all variables you want to set with set(<var_name> <value>) and pass this file to the CMake call via -C:

cmake -C <fileWithInitialValues> <pathToSrcDir>

Documentation:
https://cmake.org/cmake/help/v3.3/manual/cmake.1.html

This should would similar with cmake-gui and ccmake, but it is not a pure solution with the graphic interface.

cmake-gui generates CMakeVars.txt and CMakeCache.txt files in the build directory once you click "Configure" button. They cache all variables you configured through the GUI.

Had the same question ... and as you asked I looking up some of the options in the menu and found it. Menu Tools -> Show My Changes

Bringing up an Dialog with an edit field with content for command line options or cache file options.

yeah

p.s. I used cmake 3.11.1

The equivalent cmake command to cache a variable is explained here (-D option). Note that previous documentation was ambiguous, so take care of always checking the latest one.

Basically: 

-D<var>:<type>=<value>

You have to specify also the type to have the variable cached in the same way as through your cmake-gui procedure. Note that variable definition is necessary only the first time: if not specified anymore, the cached value will be used.

just read file named like CMakeCache.txt (iirc) in the root of build directory and see variable names there
