ERROR: Bitbake couldn't find CMakelists.txt after extraction (Yocto)

I am trying to compile Ceres solver on a yocto build (for Intel Aero drone). I earlier tried pulling using the git repository at https://ceres-solver.googlesource.com/ceres-solver/ but could not get it to fetch. So I downloaded the tar.gz file myself, uploaded it on a public domain I own and tried to compile. Here is how my bb file looks as of now. LICENSE = "CLOSED" LIC_FILES_CHKSUM = "" DEPENDS = "glog gcc libeigen" SRC_URI = "http://sidj.in/wp-content/uploads/2017/06/ceres-solver-41455566ac633e55f222bce7c4d2cb4cc33d5c72.tar.gz " SRC_URI[md5sum] = "6f24d5639bbe738e6f8ca5d7a129400e" SRC_URI[sha256sum] = "005ed7405350767f22164d9fff93b3613207eeef9cbb56afbd02335542360b16" PV = "1.0" S = "${WORKDIR}/ceres-cmake" inherit cmake pkgconfig # Specify any options you want to pass to cmake using EXTRA_OECMAKE: EXTRA_OECMAKE = "" Now I see the download getting completed, but upon running the bitbake ceres command, I get an error saying that CMakelists.txt could not be found, while it is clearly in the tar.gz file. I looked at other recipes that seem to work, and feel that the do_unpack step is not the one failing. The output of the console is: Loading cache...done. Loaded 2790 entries from dependency cache.

Am I doing something stupid or wrong?
