Any way for cmake command to use parameters in a file?

Question

cmake may take a lot of command parameters, for example

cmake -GNinja -DAAA=BBB ...

Any convenient way for Windows?

For example, save the parameters in a file like "cmake_cfg.debug", and call

camke --config_file=cmake_cfg.debug

A `custom_settings.cmake` helps, 1. set variables in the file 2. include the file to use the variables — followait, Jul 12 '21 at 12:33

If you're using bash-like a shell, you could do something like:

$ cmake $(xargs < /path/to/file) ..

In your case, the file would look like (the individual values need to be separated by whitespace chars):

-GNinja -DAAA=BBB
-DOtherParam=Value

I'm using both Windows and Linux. What about Windows? – followait Nov 22 '20 at 06:07

This will probably not work for the generator choice, but for all the cache entries you could create a cmake file using the set() commands to set cache entries and use the -C option to tell cmake to use this file to prepopulate the cache:

prepopulate_cache.cmake

set(AAA "BBB" CACHE STRING "documentation string of AAA")
...

cmake -G Ninja -C prepopulate_cache.cmake <source_dir>
