<p style="margin-top:0px; margin-bottom:0px">Hi,</p>
<p style="margin-top:0px; margin-bottom:0px"><br>
</p>
<p style="margin-top:0px; margin-bottom:0px">How do I make a variable visible in the ccmake tool?</p>
<p style="margin-top:0px; margin-bottom:0px">For example I would like the user to be able to edit BOOST_ROOT when calling ccmake, how can I do that?</p>
<p style="margin-top:0px; margin-bottom:0px"><br>
</p>
<p style="margin-top:0px; margin-bottom:0px">Right now all I see when first running ccmake is "EMPTY_CACHE", and when typing "c" to configure (which fails because some variables aren't properly set) then "e" to exit, I see the variables I have defined with
"option", and I can toggle those, but I don't see other variables. I have tried the following:</p>
<p style="margin-top:0px; margin-bottom:0px"><br>
</p>
<p style="margin-top:0px; margin-bottom:0px"></p>
<div>if(NOT DEFINED BOOST_ROOT)<br>
set(BOOST_ROOT "/usr" CACHE PATH "Root of the Boost installation")<br>
endif(NOT DEFINED BOOST_ROOT)</div>
<p></p>
<p style="margin-top:0px; margin-bottom:0px"><br>
</p>
<p style="margin-top:0px; margin-bottom:0px">But I still don't see it in the list of variables.</p>
</div>
</div>
</blockquote>
<div><br>
</div>
<div>CACHE variables are "Advanced Variables" which are not displayed unless you toggle display advanced var in either ccmake or cmake-gui.</div>
<div>In ccmake you have to hit 't' in order to see advanced variables.</div>

<p style="margin-top:0px; margin-bottom:0px"><br>
</p>
<p style="margin-top:0px; margin-bottom:0px">Additionally, is there a way to have set of variables (namely the options, as well as things like BOOST_ROOT, CMAKE_CXX_COMPILER, CMAKE_C_COMPILER) show up when first calling ccmake, instead of EMPTY_CACHE?</p>

</div>
<div>I don't know, CMAKE_<lang>_COMPILER is not meant to be set with cmake UI, they ought to be set in a toolchain or outside.</div>
<div>As noted in CMakeForceCompiler module you should not force them, use toolchain or env var before calling cmake* tool.</div>
