How can I use CMake -C option in Android Studio (gradle)? - android-studio

Question

I have to populate the CMake variable cache from a file.
I added an argument to defaultConfig.externalNativeBuild.cmake.arguments (-C options.cmake).
However, I get this:
17:05:13.520 [LIFECYCLE] [org.gradle.api.Project] loading initial
cache file options.cmake 17:05:13.521 [LIFECYCLE]
[org.gradle.api.Project] CMake Error: Error processing file:
options.cmake
The file is in the same directory as the build.gradle.
I tried providing the absolute path (with the help of projectDir variable), but it didn't change anything.
Simple reproduction
Create an empty Android app in Android Studio.
In MyApplication/app add a simple CMakeLists.txt file:
cmake_minimum_required(VERSION 3.0)
project(hello)
In the same folder add a simple options.cmake file:
set(foo "bar")
Note that this is OK for CMake:
cd MyApplication/app && mkdir bld && cd bld
cmake -C ../options.cmake ..
Now, import the CMakeLists.txt with right-click on the project and 'Link C++ Project with Gradle'
Your build.gradle should now have this:
externalNativeBuild {
cmake {
path 'CMakeLists.txt'
}
}
What I tried doing now was adding the following in defaultConfig:
externalNativeBuild {
cmake {
arguments "-C ${projectDir}/options.cmake"
}
}
But this doesn't work. Any other ideas for populating CMake cache?

It turned out to be quite easy:
Don't put space after "-C"
