Cmake contributions

Contributions to the cmake build configurations are welcome. Please use case sensitivity that matches modern (ie. cmake version 2.6 and above) conventions of using lower-case for commands, and upper-case for varibles.

CMake Style Recommendations

Indent all code correctly, i.e. the body of

• if/else/endif
• foreach/endforeach
• while/endwhile
• macro/endmacro
• function/endfunction

Use spaces for indenting, 2, 3 or 4 spaces preferably. Use the same amount of spaces for indenting as is used in the rest of the file. Do not use tabs.

Upper/lower casing

Most important: use consistent upper- or lowercasing within one file !

In general, the all-lowercase style is preferred.

So, this is recommended:

add_executable(foo foo.c)

These forms are discouraged

ADD_EXECUTABLE(bar bar.c)
Add_Executable(hello hello.c)
aDd_ExEcUtAbLe(blub blub.c)

End commands

To make the code easier to read, use empty commands for endforeach(), endif(), endfunction(), endmacro() and endwhile(). Also, use empty else() commands.

For example, do this:

if(FOOVAR)
   some_command(...)
else()
   another_command(...)
endif()

and not this:

if(BARVAR)
   some_other_command(...)
endif(BARVAR)
