[CMake] resetting CHECK_INCLUDE_FILE

[Eric Noulard]

<< re-sending to ML with complement >>

The result of the check may be cached.

If you install/remove software on which your build depends
I think the better you have to do is to throw the CMake cache all together
and re-run CMake in a pristine build tree.

The CMake cache file is:
CMakeCache.txt in your build tree.

It seems there is "include cache" files too but I don't
know how they are used by CMake.
Those files are
CMakeFiles/<target>.dir/includecache.C.

If you use separate build tree and source tree
the better/simpliest is to:

a) remove the entire build tree
b) re-run cmake
c) rebuild

Trying to PARTIALLY rebuild after installing dependencies
does not look like a good idea from my point of view.
