I get that error message when I try to use the source directory as the

With cmake, it is better to use a different folder structure for the build
- if I remember correctly something like running cmake in a clean version
of the repository but using ..
cmake -S . -B ../build
or
mkdir build
cd build
cmake ..
While I completely agree that it's better to buse a build directory, I
think it's a bug if cmake in the source dir fails, unless it is
documented not to work and it bails out early with a nice error message.
In-tree CMake builds are only partly supported currently, because of the
continued support of autoconf/nmake and conflicts between generated
files of CMake with files used by autoconf/nmake. We should be able to
fix that once support for autoconf/nmake is gone
Anyway out of tree builds are always recommended.
When doing "cmake ." you'll get the following warning at the end:
CMake Warning at gdal.cmake:872 (message):
In-tree builds, that is running cmake from the top of the source tree are
not recommended. You are advised instead to 'mkdir build; cd build;
cmake
..'. Using 'make' with the Makefile generator will not work, as it will
try the GNUmakefile of autoconf builds. Use 'make -f Makefile' instead.
