Summary

0011343: A built-in facility to disallow in-source builds would be a useful feature

Description

It is possible (and it is done on multiple projects) to disallow configuring a source tree as a build directory. The only problem is that testing for CMAKE_CURRENT_SOURCE_DIR != CMAKE_CURRENT_BINARY_DIR doesn't happen before CMake creates the CMakeCache.txt file and CMakeFiles directory.

This is a problem because if CMake detects its own config/build files in a source directory, it will act as though it has configured an out-of-source build directory, but a build in the out-of-source directory will fail.

What's needed is a 'magic' option to disallow out of source builds, that will get checked before creating any files in the source directory.
