CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

Configuration failed.

I resolved the issue with Valentin Safonnikov's comment:

"Instead changing global path, you can add the path to cmake into local.properties file in the same dir as gradlew. cmake.dir=D\:\\Android\\sdk\\cmake\\3.10.2.4988404"

Edit: I only thought it was solved. All issues were only finally solved when I uninstalled cmake 3.10 and left only cmake 3.6 installed (it kept using 3.10 even with cmake.dir=...\\3.6.... I could see this in the textual gradle output:
