Summary0015575: Ambiguous documentation for how to define a (cached) variable in cmake from command line
DescriptionAs discussed in http://stackoverflow.com/questions/30319646/ambiguous-documentation-for-how-to-define-a-cached-variable-in-cmake-from-comm: [^]

In the command line synopsis there's

-D<var>=<value>

While in the option description we read:

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

The two entries differ by a space between -D and the variable definition, and by the presence/absence of :<type>.

Does the space make any difference? What is the difference between specifying or not the type? Is it cached in any case? Is it shown in the gui afterwards?

This was partially resolved by a recent commit:

 Help: Document conversion of PATH/FILEPATH cache values to absolute paths
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=77d466ec [^]

I've updated the documentation further to clarify:

 Help: Spell '-D' option consistently across documentation
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=b0ea3673 [^]
