llvm dev - Aug 2017 - Safety of changing values of variables by editing CMakeCache.txt Vs supplying them through the command line

Hello,

I'm working on a project involving LLVM and keep shifting between the Debug
and Release build by assigning different values to CMAKE_BUILD_TYPE in
<llvm_build>/CMakeCache.txt and then building it.

I wanted to know if this was a safe alternative to re-configuring the build
after removing <llvm_build>/CMakeFiles/ and
<llvm_build>/CMakeCache.txt.

Thanks,
Sanjay

Have two build directories which each point to the the same source folder.

$ (mkdir release && cd release && cmake path/to/source
-DCMAKE_BUILD_TYPE=Release)

$ (mkdir debug && cd debug && cmake path/to/source
-DCMAKE_BUILD_TYPE=Debug)

Thanks for your response Michael !

I would have to maintain a symlink which points to either directory then.
Is that recommended ?
