[cmake-developers] [PATCH] Help: Fix elseif/endif contradictions

[Juuso Linda Lapinlampi]

From: "Juuso \"Linda\" Lapinlampi" <linda at lindalap.fi>

In CMake 3.13.x, we had this evaluation for if() conditions:

    if(a) elseif(b) else(a) endif(a)

Since CMake 3.14.0-rc1 (commit c2efb3efcd083523a73a2a9721b7101fbfc0fe0f
specifically), the sensible intention was:

> "endif", "endfunction" etc: Explain that the argument is optional and
> maintained for compatibility only

Instead of "endif", it ended up being written to the documentation as
"elseif" by the commit author (oops) to if()'s page.

    if(a) elseif(a!?) else() endif(a?)

Truthfully, endif()'s parameter should be an optional verbatim repeat
and not elseif()'s. If it wasn't, elseif() would be described to be the
same as if(). The rightful intended description is:

    if(a) elseif(b) else() endif()

This commit fixes that error.
