It was frustrating to find this silly mistake so documenting here for future visitors.

create file local.properties under your android folder if not already there with following key=value pair

cmake.dir=<path_to_cmake_folder_without_quote_and_without_bin>

e.g. cmake.dir=/use/local/cmake

Note that following won't work

cmake.dir="/use/local/cmake"

cmake.dir=/use/local/cmake/bin

For me, I am using the newest version of CMAKE from the source repo. It by default installs to /usr/local/bin/cmake.

The problem is that the error message never says that it is adding /bin/cmake to the path...

so for the future in your local.properties make like so:

cmake.dir=/usr/local/

You may want to specify the cmake version in your build.gradle file thusly [1]

android {
    ...
    externalNativeBuild {
        cmake {
            ...
            // Specifies the version of CMake the Android plugin should use. You need to
            // include the path to the CMake binary of this version to your PATH
            // environmental variable.
            version "3.10.2.4988404"
        }
    }
}

For versions downloaded by the sdk manager, I didn't need to specify cmake.dir in my local.properties. Try deleting it entirely.

I needed to specify cmake.dir when I used a version of cmake that wasn't installed from Android Studio's sdk manager. Then I had to put the path to the cmake installation directory (the one containing the bin/cmake), not the cmake binary directory directly.
