Hi Fedja,
As far as I know, the Makefiles generated from CMake cannot contain decisions.
CMake supports several output types aside from Makefiles and some of them
probably don’t support decisions. However, you could supply these arguments
within CMake call using -D option. For example
cmake -DENV=VERSION_2 <source_or_binary_directory>
creates a CMake variable just like
set(ENV "VERSION_2" CACHE)
in the CMake source file.
As you’ve mentioned already, you can access environment variables using
$ENV{variable} syntax in CMake.
Hope this helps.

Subject: [CMake] Parsing command line arguments from the make
Since I am converting existing makefile project to use cmake instead I need to
accept values that come from command line which looks like this:
VARIABLE_NAME="/home/user/project" make ENV=VERSION_2
First one is used like this:
include $(VARIABLE_NAME)/Makefile.include
Second one has this code that triggers different paths later:
ifneq ($(ENV),)
DEPLOYMENT_VERSION=$(ENV)
endif
How do I do this in cmake?
Thanks!
