llvm dev - Sep 2018 - CMake build of LLVM/clang with -DCMAKE_BUILD_TYPE=Release does not create release versions?

>because with that generator the CMAKE_BUILD_TYPE variable is ignored
 >because it is a "multi-configuration target".

thanks for the link, is that a bug in the CMake configuration (or better 
not getting any warning) or is there just documentation missing?

so i can use --config Debug or --config Release and get the correct 
results - i hope that works the build takes hours

strange is that -DCMAKE_BUILD_TYPE=Debug results in a different 
build-directory size compared to -DCMAKE_BUILD_TYPE=Release - so its not 
fully ignored?

Regarding the Debug build taking hours, are you setting the optimized
tablegen option? If you aren't the Debug build will take a very long
time. In addition, make sure you have plenty of memory, because the
link stages take up a lot on Debug builds.

LLVM_OPTIMIZED_TABLEGEN is not active - i will try that

i've got only Intel Core 2 Quad CPU Q8300/2.50Ghz and 8GB RAM for testing
not much cpu power AND memory

beware of small trap:

cmake --build . --config Release

works

cmake --config Release --build .

breaks after does not build - leaves build without errors
