Hello,
I'm finding the cmake --system-information command option to be valuable in testing different things. However it appears that it does not appear to work with -D. For example:
cmake -DCMAKE_C_COMPILER=/usr/bin/gcc --system-information system.txt
The information in 'system.txt' will not contain the defined compiler from the -D option.
I wonder if this is intended? Will it work with a toolchain file instead? Or do I need to do a real build in order to make use of toolchain files and the -D option?
Thanks,
Justin
