Hi,
One of my users reported that the filenames of several header files
appeared in the advanced section when using CMakeSetup/ccmake.
Eventually I tracked down the problem to some macro using find_file.
It turns out that the variable where find_file (and family) reports the
result is automatically cached whether I like or not. My code was using
"mark_as_advanced" but that was not enough as my users just didn't want
the variable in the GUI at all.
Eventually I came up with the following trivial macro "mark_as_internal"
which I used to hide away these unwanted variables:
macro ( mark_as_internal _var )
set ( ${_var} ${${_var}} CACHE INTERNAL "hide this!" FORCE )
endmacro( mark_as_internal _var )
but I wonder:
Is there a better way?
Shouldn't ALL the commands that create/define variables (like find_*)
accept a NO_CACHE option? or at the very least an INTERNAL option?
TIA
mark_as_advanced is the usual path.
