How do I set a property to the output of a command in msbuild/xbuild
- by Nils
In msbuild/xbuild I'd like to have a "libPath" property which can be ovveridden on the commandline using /p:libpath="/path/to/all/libs". But when this property is undefined I want to call pkg-config --retrieve-Path somePackage to get the current systems path.
I thought like here I need the output of a command to be stored in a Property.
The command always returns one line of output.
I have tryied something like
<PropertyGroup>
<LibPath />
</PropertyGroup>
<Task ....>
<Exec Command="pkg-config --retrieve-Path somePackage"
Condition="$(LibPath)' == ''">
<OutputTaskParameter="output"
PropertyName="LibPath" />
</Exec>
</Task>
But that didn't work.
