Using CMake with GNU Make: How can I see the exact commands?


It is convenient to set the option in the CMakeLists.txt file as:


I use CMake with GNU Make and would like to see all commands exactly (for example how the compiler is executed, all the flags etc.).

GNU make has --debug, but it does not seem to be that helpful are there any other options? Does CMake provide additional flags in the generated Makefile for debugging purpose?

I was trying something similar to ensure the -ggdb flag was present.

Call make in a clean directory and grep the flag you are looking for. Looking for debug rather than ggdb I would just write.

make VERBOSE=1 | grep debug

The -ggdb flag was obscure enough that only the compile commands popped up.
