Hi,
I'm trying to use Qt Creator with a CMake project managed by someone else, which relies on environment
variables to specify a source location, install target on the source tree etc. I'm wondering how I
might set up the relevant data in the Qt Creator build environment. I know how to add extra variables,
but what do I specify as values? I can just type in the locations, obviously, but it would be nicer if
I could reference the current project location or source directory or whatever as stored in Qt Creator.
I've tried using Qt Creator variables as documented in
https://urldefense.proofpoint.com/v2/url?u=https-3A__doc.qt.io_qtcreator_creator-2Dbuild-2Dsettings.html-23using-2Dqt-2Dcreator-2Dvariables&d=DwIGaQ&c=KV_I7O14pmwRcmAVyJ1eg4Jwb8Y2JAxuL5YgMGHpjcQ&r=Q0oqxzgUp3xCCIiJDwS-RbNDndQ-KZDhj8wwveNoqU4&m=eIat5wgzJOrmWaHHpH3GyO-4NNQwVhic-bboWr4iZsw&s=pNy0uv96Ty6PHUePBD5M-2KambQeU1WgKKK-huK-fcI&e=,
but it looks like these aren't actually expanded in this context - if I set a variable to, say,
%{sourceDir} I get that exact value in the environment, as opposed to the current source directory. Is
that the expected behaviour? Any other ideas?
Actually, for the build steps, perhaps it would be possible to set up the environment on
the command like rather than as part of the Qt Creator settings, but the variables are
also needed by the initial cmake step, where you can't really specify "complex"
commands.
Another slight issue is that I need to set up the same variables for multiple build configurations
related to the project, and the only way I can find to do that i Qt Creator, is to duplicate the
set-up on the "Build Setup" page for each and every configuration. Is there a way a
shared environment can be set up instead? When I say "shared" I mean shared within the
project or possibly the kit, not system-wide.
Kits have an “Environment” settings,
OMG. There it is, right between "Compiler" and "Debugger". I have
completely overlooked that before. Several times. Even when I was
searching specifically for it. So that solves part of the problem in a way.
and that should support Qt Creator variables (like
%{CurrentProject:NativePath}), maybe that solves your issue?
Unfortunately, it does not look like variables are supported; I get the
literal text entered in the environment, and not the contents of the
variable. Is that actually different on your system? I don't have an
entirely new Qt Creator as I'm using a pre-built version from the "EPEL"
repository on a CentOS 7 system...
Note that to test, I have just added the command "env" as a build step.
It prints the expected list of variables, including ones set up in the
kit, but like I said, I see variable references rather than variable
contents. Is there a chance that they are somehow magically replaced later?

(They also have a similar “CMake Configuration” setting for sharing that
between projects with the same Kit.)
