Cannot find input file: `sdl2-config-version.cmake.in' error when installing sdl2 on Ubuntu 18.04

Hi,

I am trying to install SDL2 on a VMWare pro 15 Ubuntu VM running on Windows 10.
I am using the following directions per the SDL Wiki:

hg clone https://hg.libsdl.org/SDL SDL
cd SDL
mkdir build
cd build
…/configure
make
sudo make install

The …/configure command results in:
… (omitted due to “new user link restriction” )
checking for linker option --enable-new-dtags… yes
configure: creating ./config.status
config.status: creating Makefile
config.status: creating sdl2-config
config.status: creating sdl2-config.cmake
config.status: error: cannot find input file: `sdl2-config-version.cmake.in’

After my initial attempt, I installed cmake, reran the configure with the same result.

Hopefully, someone can show me how to resolve this.
Thanks in advance,
Larry Evilsizer
