Hi,

So, what about step 5 in the findpackage docs..
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:find_package

--->
5. Search project build trees recently configured in a CMake GUI. This 
can be skipped if NO_CMAKE_BUILDS_PATH is passed. It is intended for the 
case when a user is building multiple dependent projects one after another.
<---

Can i disable this alltogether? On some of my subprojects that do a 
find_package i have no incluence. And given the fact that some of the 
provided find_package scripts are suboptimal, i really don't want to 
find any stuff lying around.

Again: Can this be disabled?

(like passing DNO_CMAKE_BUILDS_PATH to cmake?)

Reason: if I configured something wrong, like ${package}_DIR or the 
HINT, I want the build to fail, and not to silently continue with some 
other binaries.

There are several builds running, doing similar stuff. It can happen 
that one build creates a library, that by accident may be found in 
another build task.

Regards,
Thomas
