Hi @BartoszKosiorek-TomTom
Thanks for reporting this.
There are no plans to allow command line global environment variables, but to rely on system ones, like:
$ MYVAR=1 conan install ...
# or
$ set MYVAR=1 && conan install ...
In general, it would be discouraged to rely on env-vars for Conan related control (the recommended way to pass information to Conan is the new conf
system, with command line -c
and profile [conf]
, and global.conf
). For tools env-vars, the [buildenv]
would be recommended in profiles.
Thanks @memsharded for instant response.
The conf
system, is nice replacement for -e
. Unfortanately conf
is missing possibility of setting only for specific package:
Specific package environment variables (-e zlib:SOME_VAR="SOME_VALUE"). These variables will be defined only in the specified packages (e.g., zlib).

Unfortanately conf is missing possibility of setting only for specific package:
Not really. The conf
syntax also supports definition per package, both in CLI and in profiles with patterns and package references like: -c mypkg/*:<conf>=<conf_value>
More info in https://docs.conan.io/2/reference/config_files/global_conf.html#configuration-patterns
With Conan 2 the
-e
,-e:b
and-e:h
parameters was removed:There is missing information in documentation about it (e.g. in migration guide: https://docs.conan.io/1/migrating_to_2.0/general.html#environment-variables) and how to replace it.
