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?

CMake 3.14+ you can simply specify the verbosity of the build tool.
Before CMake 3.14
When you run make, add
VERBOSE=1
to see the full command output. For example:Or you can add
-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON
to the cmake command for permanent verbose command output from the generated Makefiles.To reduce some possibly less-interesting output you might like to use the following options. The option
CMAKE_RULE_MESSAGES=OFF
removes lines like [ 33%] Building C object..., while--no-print-directory
tells make to not print out the current directory filtering out lines likemake[1]: Entering directory
andmake[1]: Leaving directory
